The Liquid Limit Device, or Casagrande Apparatus, is a fundamental tool in geotechnical engineering and soil mechanics for determining the liquid limit of soil samples. It is manually operated and consists of a brass cup, a grooving tool, and a counter to record the number of blows. During testing, a soil sample is placed in the brass cup, a groove is made, and the cup is repeatedly dropped until the groove closes over a standard distance. This process helps determine the moisture content at which soil transitions from a plastic to a liquid state.

Includes brass cup, grooving tool, and blow counter
Measures liquid limit (plastic-to-liquid transition)
Durable construction suitable for lab use

Salt Spray Chambers are specialized testing equipment used to simulate and accelerate the corrosive effects of salt-laden environments on metals, coatings, and other materials. Designed with corrosion-resistant bodies made of SS316 stainless steel or fiber-reinforced plastic (FRP), these chambers ensure durability and longevity in harsh laboratory conditions.
The chamber temperature ranges from ambient to 80C with an accuracy of 1C, while the saturated air barrel maintains temperatures between 40C and 49C. The salt solutions pH is controlled between 6.5 and 7.2 to replicate standard corrosive conditions. The test air pressure is maintained between 0.7 and 1.2 kg/cm to ensure proper atomization of the salt solution.
Equipped with a digital display, the chamber allows real-time monitoring of temperature and humidity, and a programmable timer facilitates precise test durations. Specimens are suspended using hanging rods, and safety features such as over-temperature protection ensure safe operation during extended testing cycles.
