REPLACEMENT OF SENSOR
Tester 5 series has replacement sensors which can be replaced in case it expires of damages.
1) To replace the sensor unscrew the dial in anti-clock wise.
2) Pull out sensor from unit body.
3) Put a new sensor by matching correctly the sign of dent.
4) Be sure that all the gaskets are good and in correct position.
5) Screw the dial tightly.
SENSOR MAINTENANCE
Before first time use or after long time dry storage, leave the probe in tap water or storage solution
for at least 30 minutes to activate the sensor.
EC2620-Cond1 / EC2630-Cond5:
- Rinse the probe with distiller water or sample before use.
- For short time storage use distiller water. For long time store dry.
PH2620-pH1 / PH2630-pH5 pH5 Food / PH2720-ORP5 / EP2000-PC5:
- Rinse the probe with distiller water or sample before use.
- Store the probe in storage solution for regular use. For long time store dry.
- Never store pH sensor in distilled water
Never touch conductivity probe with paper, for cleaning purpose only rinse with distilled water.
If touched the probe may damage.
