Pen type multi-function tester

●   With automatic calibration, automatic temperature compensation, data storage,   pH electrode failure reminder, low voltage display, automatic shutdown and   other intelligent features.

●   Large LCD display with line graph for simultaneous display of measured and   temperature values.

●   For the first time, a planar pH electrode was used in its class. Can be used   for pH testing of various media, including solutions, trace solutions, and   wetted solid and semi-solid surfaces such as skin, meat products, fruit,   cloth, paper, cheese, and more.

●   The total residual chlorine in the aqueous solution is measured and includes   free chlorine (Cl2), hypochlorite (OCl-) and nitrogenous compounds of   chlorine such as chloramine T. Use one tablet per test without additional   complex reagents.

●   Complies with IP57 waterproof rating, with calibration solution, measuring   cup and suitcase.
