1. Treat your pH meter and electrode with care - it contains a hand made glass probe
2. Do keep the probe wet when stored : use storage solution, buffer or even tap water
3. Do remember to re-calibrate your pH meter from time to time to maintain accuracy
4. Don't worry about white crystals around electrode : they are normal and wash off with water
5. Don't subject the meter to impact or excessive heat
6. Don't let the electrode become dry

If you are looking for a compact pH meter then look no further than these two new meters:

• Dual level display shows both pH and Temp.
• °C or °F temperature display selection
• Battery life indication
• Replaceable pH electrode
• Waterproof and floating case
• Automatic calibration
• Hold display reading function

Two Models :

HI 98127 : pH 0.0 to 14.0 with a resolution of 0.1 pH and accuracy of ± 0.1 pH

HI 98128 : pH 0.00 to 14.00 with a resolution of 0.01 pH and accuracy of ± 0.01 pH

Both models come with a sachet of 7.01 pH buffer

A wall mounted continuous pH monitor and indicator housed in a waterproof case and with a visual alarm indicator to alert users when a set pH value is exceeded.
The HI-981402 is powered by a 12volt feed and displays pH to 0.1pH on the clear LCD display.
The case is water and dust proof and incorporates a moulded hook to facilitate positioning on a hook. The pH electrode connection has additional protection against water and dust allowing the meter to be used in damp and humid environments.
A user programmable alarm provides a visual indication via a Red LED light on the front of the instrument, that a previously selected pH point has been exceeded.
