Specifications

These simple 1-point calibration testers are designed for the
Horticultural and Agricultural market.
They are built in a one-piece splash-proof casing and they
are immersible up to the LCD.
All models have Automatic Temperature Compensation and
the temperature sensor housing is made out of 316 inox
steel instead of plastic.
This ensures 100 times faster readings and higher accuracy.
Models available are:
• C61: Conductivity tester low range
Range: 0 to 1999 µS/cm
• C62: Conductivity tester high range
Range: 0.00 to 19.99 mS/cm
• T71: TDS tester low range
Range: 0 to 1999 ppm
• T72: TDS tester high range
Range: 0.00 to 10.00 g/L (ppt)

Temperature has a huge influence on TDS and EC, on the basis of a 2% error per degree
Celsius. Even small temperature differences between the measured solution and the
measuring instrument can lead to large reading errors. For instance, if the solution's tem-
perature is 15°C, and the tester’s is 35°C, the reading error is (35-15x2%) 40%.
Conventional testers with plastic casings for their temperature sensors also slow response
times. It can take at least 10 minutes for conventional testers to fully compensate
temperature differences. This causes reading error.
Sharp tester's new stainless steel encased temperature sensors can compensate in
seconds, no matter how large the temperature difference. Sharp tester’s fast response
time guarantees high accuracy.
