Measures:
pH, ORP, TDS, Resistivity, Conductivity, Temperature and Calculates Free Chlorine
Easy to Calibrate
Advanced Features
3 solution standards for greatest accuracy in diverse applications
Fully automatic temperature compensation
User adjustable temperature compensation (up to 9.99%°C)
which also allows TC to be disabled for applications requiring non-compensated readings.
User adjustable conductivity/TDS conversion ratio for greater accuracy when measuring solutions
not contained in the microprocessor.
Auto-shut-off maximizes the life of the single 9V battery to more than 100 hours/5000 tests.
Non-volatile microprocessor provides data back-up, even when the battery is changed.
