Specification

This Milwaukee T 71 simple 1-point calibration TDS tester is designed for the Horticultural and Agricultural market. It is built in a one-piece splash-proof casing and It is immersible up to the LCD.

This model have Automatic Temperature Compensation and the temperature sensor housing is made out 316 inox steel instead of plastic. This ensures 100 times faster readings and higher accuracy.

Specification:
Range : 0 to 1990 ppm
Resolution : 1 ppm
Accuracy : ± 2% full scale
Temperature compensation: automatic from 5 to 50 C
Battery life : 350 hours
Dimensions : 155 x 45 x 25 mm

Temperature has a huge influence on TDS and EC, on the basis of a 2% error per degree Celcius. Even a small temperature differences between the measured solution and the measuring instrument can lead to a large reading erros. For instance, if the solution’ s temperature is 15 C, and the tester is 35 C, the reading error is ( 35 - 15 x 2% ) = 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 tempeatures differences. This cause 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.
