TDS111N Non-Bluetooth TDS + Temperature tester (0 to 10.0 g/L) by Jenco

Waterproof, economical TDS/temperature tester with long useful life.

Like its Bluetooth sibling, the Wand Non-Bluetooth Series' main focus is to deliver accurate and repeatable TDS results easily and affordability. This was accomplished by starting Jenco's longest running and very popular tester series and updating it with better electronics for better accuracy, replacing the potentiometer with buttons with tactile feedback and protecting the upgraded internals with an IP67 waterproof housing.

Improved Reading Quality

• 1 Point calibration
• ±1% F.S. accuracy

Simple Operation

• Clear, large LCD displays TDS and temperature
• Button operations with tactile feedback
• IP67 waterproof housing

TDS60000/G Conductivity Solution, 60,000ppm/60,000uS, 1Gal by Sensorex

TDS/Conductivity instruments and sensors must be calibrated together. For a single-point calibration, select the one solution that approximates the expected conductivity or ppm level of total salts. Mixed Salt standards are the most frequently used in the field to sample naturally occurring water sources, boiler feed water, or cooling tower water. Typical river water, well water, or lake water sample will contain a mixture of several different salts. Sensorex Mixed Salt standards simulate a "Natural" mixture of common salt compounds found in these sources. Sodium sulfate, sodium bicarbonate, and sodium chloride salts are blended to provide a representative value. There are certain applications where Single Salt Solutions are preferred. NaCl Solution is routinely used to calibrate instruments measuring Sea Water or brackish water samples. Reagent grade salt and high resistivity DI water is compounded for accurate results. KCI Single Salt Solution may be used with conductivity meters that read directly in Siemens or Ohms. KCI (potassium chloride) is established as an international calibration standard for conductivity measurement. Choose the conductivity calibration solution that is right for your application.
