Features
| ● Configure pH, residual chlorine, ORP three electrodes, the instrument can automatically identify the electrode. | 
| ● 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. |
