Specialty Hydrometers

• For soil, salt and battery acid analysis.

Make testing simple--pick the hydrometer that matches your specific testing task.

Determine the specific gravity of soils with Nos. 77124 and 77125. Both are calibrated at 68°/68°F and meet ASTM specifications. Length: 280mm. No. 77126 is graduated in percent of saturation of sodium chloride in water. Temperature of standardization: 60°F. Length: 300mm. No. 77127 measures the specific gravity of battery acid and comes with a siphon set that includes a glass tube with plug and rubber suction bulb installed on the upper end, and a rubber nozzle with clamp for the lower end of the glass tube. Rubber parts are made of buna nitrile; more durable and resistant to chemicals than conventional rubber. Calibrated at 77°F. Length: 165mm.
