Oakton Waterproof Microprocessor SaltTestr 11 Pocket Meter, 0.0 to 10.00 ppt TDS Range

The Oakton 35662-52 Salt Testr is a handheld, waterproof and dustproof pocket meter that measures salinity, floats, if dropped in liquid, is factory-calibrated against sodium chloride (NaCl) standard solution for reliability, and has + or - 1% full scale accuracy. A portable pocket meter is commonly used to measure the salinity of substance, particularly NaCl-based samples, in aquaculture, aquariums, fish farms, food processing, swimming pools, and in environmental and waste water treatment.

This microprocessor meter features one-point, push-button calibration located in the battery compartment to avoid accidental recalibration, and has Automatic Temperature Compensation (ATC) for accurate readings in fluctuating temperatures. It has a replaceable sensor to extend the life of the tester. The meter’s waterproof and dustproof housing is Valox resin, and has Ingress Protection (IP) 67-rating for protection against solid objects or liquids. Its stainless steel sensor tip is both durable and chemical resistant. It has a dip-style sensor for immersion. The meter displays full readings to obtain actual test values and to eliminate the need to multiply the readout. It has a dual-display, LCD upright screen to display selectable temperature in degrees C or F. It has a hold function which freezes readings for recording, and an auto shut-off function that automatically turns the tester off after 8.5 minutes of nonuse to extend battery life. A lanyard loop on the top of the battery cap secures attachment.

The 35662-52 Salt Testr comes with an integral stainless steel sensor, has ATC from 0 to 50 degrees C (32 to 122 degrees F) with ATC coefficient 2% per degrees C, 1.11% per degrees F, 25 degrees C reference temperature, and an operating temperature of 0 to 50 degrees C (32 to 122 degrees F). Calibration standard range calibrated to 4.4 ppt NaCl. Salinity range is 0 to 10.00 ppt, resolution 0.10 ppt, accuracy 0.00 to 7.00 ppt + or - 1% full-scale, above 7.00 ppt + or - 3% full scale. It comes with a 316 stainless steel electrode and glass-filled thermoplastic polyester. Its dimensions are 6.5 (h) x 1.5 (w) inches (16.8 x 3.8 cm) and it weighs 3.25 ounces. The meter works with four 1.5 V alkaline batteries (not included) for up to 150 hours of continuous use. Alternate battery replacement model LR44 (not included) may be used.

A salt meter measures salinity of a substance and is commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics, and water-testing and for scientific applications.
