Oakton Waterproof ECTestr 11 Pocket Meter, 0 to 2000 microseconds; 0 to 20.00 milliseconds TDS Range
USD 67.58 The Oakton 35662-30 ECTestr 11 is a handheld, waterproof and dustproof pocket meter that reads dual-range measurements, measures electrical conductivity (EC), and floats, if dropped in liquids. A portable pocket meter is commonly used to measure the EC of substance in aquaculture, aquariums, fish ponds, food processing, swimming pools, and in environmental treatment. This meter has a low range to measure EC (μS) in natural water, to verify reverse osmosis system operation and tap water quality, and to check nutrient solution concentration in hydroponics applications. The tester’s high range measures EC (μS) in salt water, waste water, cooling tower water, and boiler condensate. It’s used to check nutrient solution concentration in hydroponics applications, measure the salinity for ponds and recirculating systems, and to check saline and chemical levels in pools and spas. The meter has automatic temperature compensation (ATC) for accurate readings in fluctuating temperatures, and single, or one-point per range, push-button calibration for more precise readings. It features a replaceable, two-pin type electrode to extend meter life. Its stainless steel sensor tip is both durable and chemical resistant, and the sensor is dip-style to immerse and read. It has an Ingress Protection (IP) 67-rated waterproof, dustproof, Valox resin housing for protection against solid objects or liquids. The meter has an upright, dual-line screen for ease of viewing, and temperature readout with simultaneous display in degrees C or F. It has a hold function which freezes readings for recording, an auto shut-off function to extend the life of the batteries, and a lanyard for attachment. The 35662-30 ECTestr 11 comes with a replaceable stainless steel sensor, has ATC from 0 to 50 degrees C (32 to 122 degrees F), and operating temperature of 0 to 50 degrees C (32 to 122 degrees F). Temperature display is 0 to 50 degrees C (32 to 122 degrees F), 0.1 degree C resolution, + or - 0.5 degrees C accuracy. ATC coefficient 2% per degrees C, 1.11% per degrees F, 25 degrees C reference temperature. Wetted materials: 316 stainless steel (electrodes) and HDPE/Valox housing. EC range is 0 to 2000 μS; 0 to 20.00 mS, resolution 10 μS; 0.10 mS; accuracy + or - 1% full-scale. Calibration 2-point manual or automatic (1413 μS; 12.88 mS). Calibration standard range is 300 to 1999 μS, 3 to 19.90 mS. The dimensions are 6.5 (h) x 1.5 (w) inches (16.8 x 3.8 cm) and it weighs 3.25 ounces. The tester works with four 1.5 V alkaline batteries (not included) for up to 100 hours of continuous use (approximately 600 tests per battery pack). Alternate battery replacement model LR44 (not included) may be used. Conductivity is the ability of a solution or material to conduct an electrical current. An EC meter measures the electro-conductivity of a solution and is commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics, and water-testing and for scientific applications. Oakton Instruments manufactures an array of scientific instruments for research, industrial, and educational uses. Since 1991, Oakton has distributed a wide variety of instruments such as meters, electrodes, and transmitters. Oakton is based in Vernon Hills, IL, and has facilities in Europe, Asia, and China.

Oakton Waterproof Portable Microprocessor TDSTester High Pocket Meter, 0 to 10.00 ppt Range
USD 75.00 The Oakton 35661-21 TDS Testr High is a handheld, waterproof and dustproof pocket meter that measures Total Dissolved Solids (TDS), floats, if dropped in liquid, and has + or - 1% full scale accuracy. A portable pocket meter is commonly used to measure the TDS of substance in aquaculture, aquariums, fish ponds, food processing, swimming pools, and in environmental treatment. This microprocessor meter features a TDS range of 0 to 10.00 ppm for measuring TDS in salt water, waste water, cooling tower water, and boiler condensate. It is also used for checking nutrient solution concentration in hydroponics applications, measuring salinity for ponds and recirculating systems, and checking saline and chemical levels in pools and spas. It has 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. The meter displays full readings to obtain actual test values and to eliminate the need to multiply the readout. 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. It has a transparent, protective cap to reduce contamination and protect the sensor. The cap keeps the sensor moist when stored upright, and can be used as a container for sensor-conditioning, or on-site calibration. A lanyard loop located on the top of the battery cap secures attachment. The 35661-21 TDSTestr High pocket meter comes with an integral stainless steel sensor, has ATC from 0 to 50 degrees C (32 to 122 degrees F), and an operating temperature of 0 to 50 degrees C (32 to 122 degrees F). Calibration standard range is 3 to 10.00 ppm, with ATC coefficient Beta=2% per degrees C, 1.11% per degrees F, 25 degrees C reference temperature. TDS range is 0 to 10.00 ppt, resolution 0.10 ppt, accuracy + or - 1% 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 100 hours of continuous use (approximately 600 tests per battery pack). Alternate battery replacement model Eveready 357BP silver oxide (not included) may be used for approximately 140 hours of continuous use. TDS, such as salts and minerals, contribute to the conductivity of a solution. A TDS meter measures conductivity of a substance and converts it to a TDS reading. TDS readings are commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics, and water-testing and for scientific applications. Oakton Instruments manufactures an array of scientific instruments for research, industrial, and educational uses.
