Feature
●(High Precision) Large and clear LCD, easy to read and accurate measurements. The tester is made of high quality electronic components to ensure high precision. The resolution of the ORP tester is very sensitive to 1 mv
●Wide application: Suitable for water sources, aquariums, hydroponics, pools, and other water systems. Compact and portable pen design, easy to operate and store
●(ORP meter) When checking the ORP value, it usually takes several minutes to 10 minutes. Wait for the value to be stable and jump very slowly or read the display value as measurement. The ORP and air display values are jumping, but it is a normal phenomenon without regular change
●Specifications: Model: ORP-169. Measurement range: -1999 - 1999mv Resolution 1 mV Accuracy: ±5mV Operating voltage: 4*1.5V (AG-13 battery) (not included) Working temperature 0℃-50℃ Correction: One Point Correction Dimension: 188*35*35mm / 7.4*1.4*1.4in Weight: 290g / 10.2oz
●Note: There is a white crystal salt around the electrode, which is a normal phenomenon of ORP electrodes. Only when the electrode is submerged in clean water, it will melt and disappear
