We offer the best product range of Combo PH TDS Tester, PH Temperature Meter, Tds Meter, Professional Waterproof Portable PH Meter and Laboratory Research Grade Benchtop PH Meter.
The HI98129 is a highly accurate, waterproof pH meter that can also measure EC/TDS in the low range (0 to 3999 S/cm EC/ 0 to 2000 ppm TDS) and temperature. This floating, waterproof combination tester has an easy to read, LCD and an automatic shut-off. In addition, pH and EC/TDS readings are automatically temperature compensated (ATC) to prevent temperature-related variations in your measurements. For EC/TDS readings, the EC/TDS conversion factor (CONV) is selectable by the user, as well as the temperature compensation coefficient (BETA).
Replaceable pH Electrode CartridgeThe HI98129 tester features an easy to replace pH electrode cartridge with an extendable cloth junction. The extendable cloth junction helps increase electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted. Also, the sturdy, snap-in connector means there are no pins to bend or break!
High Accuracy EC/TDS Graphite ProbeThe graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits in the solution. The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings.
The HI98191 is a rugged, portable pH/ORP/ISE meter with the performance and features of a benchtop meter. This professional, waterproof meter complies with IP67 standards and measures pH, ORP, ISE, and temperature. The HI98191 is supplied with all necessary accessories to perform a pH/temperature measurement packaged into a durable carrying case.
The HI5522 is an advanced research grade benchtop pH/mV/ISE/EC/TDS/Salinity/Resistivity meter that is completely customizable with a large color LCD, capacitive touch keys, and USB port for computer connectivity. The HI5522 is rich in features including ISE incremental methods, data logging, alarm limits, comprehensive GLP, and many more while retaining simplicity in use with both dedicated key for routine operation and virtual keys that guide the user through setup options. The HI5522 ensures confidence in pH measurements with the exclusive Hanna Instruments CAL Check feature that alerts the user to potential problems during calibration including if the buffer is contaminated or the probe needs to be cleaned
The Hanna Instruments HI99171 is a durable, waterproof, and portable pH and temperature meter designed specifically for leather and paper analysis. Automatic calibration is performed at one or two points with two sets of buffers. All calibration and measurement readings are automatically compensated for temperature variations.
The HI99171 uses the HI1414D glass body, amplified pH electrode that offers numerous features that improve pH testing for surface measurements. The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and calibration instructions.
pH is an essential measurement throughout the entire cheesemaking process. From the initial measurements of incoming milk to the final measurements of ripened cheese, pH is the most important parameter for cheese quality and safety control.
Acidification of milk begins with the addition of bacterial culture and rennet. The bacteria consume lactose and create lactic acid as a byproduct of fermentation. The lactic acid produced will cause the pH of the milk to go down. Once the milk reaches a particular pH, the rennet is added. The enzymes in rennet help to speed up curdling and create a firmer substance. For cheesemakers that dilute their rennet, the pH of the dilution water is also critical; water that is near pH 7 or higher can deactivate the rennet, causing problems with coagulation.
Once the curds are cut, stirred, and cooked, the liquid whey must be drained. The pH of whey at draining directly affects the composition and texture of the final cheese product. Whey that has a relatively high pH contributes to higher levels of calcium and phosphate and results in a stronger curd. Typical pH levels at draining can vary depending on the type of cheese; for example, Swiss cheese is drained between pH 6.3 and 6.5 while Cheddar cheese is drained between pH 6.0 and 6.2.
During brining, the cheese soaks up salt from the brine solution and loses excess moisture. The pH of the brine solution should be close to the pH of the cheese, ensuring equilibrium of ions like calcium and hydrogen. If there is an imbalance during brining, the final product can have rind defects, discoloration, a weakened texture, and a shorter shelf life.
Cheeses must fall within a narrow pH range to provide an optimal environment for microbial and enzymatic processes that occur during ripening. Bacterial cultures used in ripening are responsible for familiar characteristics such as the holes in Swiss cheese, the white mold on Brie rinds, and the aroma of Limburger cheese. A deviation from the ideal pH is not only detrimental to the ecology of the bacteria, but also to the cheese structure. Higher pH levels can result in cheeses that are more elastic while lower pH levels can cause brittleness.
The HI99165 uses the stainless steel FC242D amplified pH electrode. This specialized electrode offers numerous features that improve pH testing for cheese producers. The robust stainless steel sheath paired with the conical sensing tip allows for penetration in cheese at various points throughout the production process. An integrated temperature sensor also ensures that all pH measurements are compensated for temperature without the need for a separate temperature probe.
The most important parameters needed for water analysis, especially in drinking water, can be measured with Hannas HI93102 portable meter. This instrument not only measures turbidity, but also free and total chlorine, cyanuric acid, pH, iodine, bromine, and low range iron. Measurements are made quickly and accurately through a sophisticated, yet easy-to-use microprocessor. Users can select between pre-programmed calibration values or calibration points can be customized at a specified concentration or relative absorbance of the sample.
The HI93102 offers many features that appeal to use in the field as well as in laboratory settings. The exclusive cuvette locking system ensures that the cuvette is inserted into the measurement cell in the same position every time to maintain a consistent path length. Up to 25 measured samples can be stored in memory, together with time and date. Miniaturization of the electronics has made it possible to offer unsurpassed accuracy and quality in a portable unit weighing just one pound.
Features at-a-glance
AMCO AEPA-1 Primary Turbidity Standard-The AMCO AEPA-1 standards for the turbidity range of the HI93102 are recognized as a primary standard by the USEPA. These non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density. The standards are reusable and stable with a long shelf life.
LoggingThe HI93102 allows users to log up to 25 measurement readings. Measurement logs can easily be recalled with the press of a button and a reminder will appear if the memory becomes full. The logging mode can be enabled or disabled.
GLPWith a press of the GLP button on the face of the meter, users can view the date, time, and two calibration values of the current mode.
Auto-shut Off-Automatic shut off is selectable after 10, 20, 30, 40, 50, or 60 minutes of non-use when the meter is in measurement mode. This feature prevents wastage of batteries in the event the meter is accidentally left on.
Battery Status Indicator- The status of the battery is monitored during every measurement cycle. An indicator will warn the user when the amount of battery life left is not sufficient to take reliable measurements.
Error CodesHelpful diagnostic codes appear on the display alerting to problems including low light, high light, or sample out of range.
