Our Products
We are leaders in the market for providing best range of 671 Digital Salinity Meter, Digital Colony Counter, 1801 Microprocessor Dissolved Oxygen Meter, 801 & 811 Dissolved Oxygen Meter and 831 Dissolved Oxygen Meter
Ei’s Digital Salinity Meter model 671 is an ideal instrument for measurement of Salinity of aqueous solutions. They use the latest microcontroller technology to measure the Salinity in three ranges from 2 ppt to 50 ppt. The appropriate range is automatically selected by the instrument. The Resolution is 0.001 ppt to 1 ppm in the lowest range. The cell constant is flashed on a digital display and can be adjusted from the front panel. Facility is also provided for automatic measurement of cell constant with a known standard solution.
This instrument is ideal for monitoring salt contents in water and soluble salts in soils. This is extremely useful instrument for agriculture and soil analysis labs, swimming pools, fertilizer plants, mineral water plants, petroleum refineries, textile plants etc.

The most time consuming part of carrying out a microbial count is the actual counting process on petri-dishes. Digital Colony Counter is designed for quick and accurate counting of bacterial and mould colonies in petri dishes. Feature packed and easy to use, this is an indispensable bench top tool for the busy microbiologist.
It is designed for rapid and accurate counting of bacterial and mould colonies. Simply place the petri dish on the illuminated pad and touch the dish with the pen provided to mark each colony in turn. This causes a count to be registered on the digital display and an audible tone confirms each count made. Marking the dish with the pen avoids missing colonies or double counting. The digital count on the display can be reset manually any time by pressing reset key provided.
Optimum viewing of colonies is aided by peripheral glare free illumination graticuled disc provided in the instrument. The magnifier magnifies the colony area. This is an indispensable tool for the microbiologist.

EI Digital Antibiotic Zone Reader provides the user, distance in mm with accurate and fast method for determining the strength of antibiotic material. It functions by measuring the diameter from 0 to 80.0 mm of an inhibition zone in a petri-dish.
Wells are created on a petri-dish, prepared with agar – agar solution and inoculated with bacteria. After incubation, the bacterial growth cover the dish except for a circular inhibited zone around each disc, it being a function of the strength of the antibiotic.
The zone reader accurately measures the diameter of the inhibited zone to 0.1 mm within range of 0 to 80.0 mm diameter. Light is passed through the transparent and semitransparent portions of the agar from a source at base towards up. It then passed to a reflecting mirror supported by an arm above the unit, which reflects the light to glass prism mounted at the front of the unit and magnified image of the zone of inhibition is clearly visible on the prism.
