(5) R72608 has a battery compartment inside. Users can buy and install rechargeable 18650 lithium battery, 3 sections total. A single rechargeable lithium battery voltage is 3.7V, and the capacity is recommended at 5000mah. The installation of rechargeable lithium battery steps are as follows: 1: Remove the four screws around the battery cover 2: Insert three 18650 lithium batteries. -
Page 15: Ph Sensor Use
6.4 PH Sensor Use The water level of the water you plan to measure the pH value of is recommended to be higher than the spiral curve on the pH sensor. Spiral curve Note: (1) The sensor is recommended to be installed with angles higher than 15 degrees. (2) Horizontal or upside-down position is not allowed. -
Page 16: Ph Sensor Maintenance
6.5 PH Sensor Maintenance When measuring the pH sensor, it should be cleaned in distilled water (or deionized water), and the filter paper should be used to absorb moisture to prevent impurities from being introduced into the liquid to be tested. 1/3 of the sensor should be inserted into the solution to be tested. -
Page 17: Important Maintenance Instruction
PH sensor can be placed in water for a long time. If PH sensor is not applicable, please add some water to the sponge in the protective shell of the probe, and then install the protective shell to the probe position. PH sensor can not be exposed to the sun, and should be placed in a humid environment.
