• The most popular waterproof meters on the market
• Both meters are housed in rugged, waterproof, ABS casings that are built to last
• READY function which will display only when the electrode has stabilized
• Dual level display with graphic symbols

These are microprocessor-based pH meters in waterproof casings. They measure both pH and C as well as ion concentration and ORP in the mV range.
Both meters are housed in rugged, waterproof, ABS casings that are built to last. The Auto-Instruction feature guides the user step-by-step through the calibration process with graphic symbols. Unlike conventional microprocessor pH meters that offer only the standard pH buffer solutions of 4.01, 7.01 and 10.01 for calibration, these meters also allow calibration at the important NBS (NIST) buffers of 6.86 and 9.18. Because the electrode requires a certain amount of time to stabilize between buffers, the meter will display the READY symbol only when the electrode has stabilized.
The powerful software of these meters will allow 1 or 2 point calibration using any of the 5 memorized buffers. This is an important feature in field measurements, since if you end up with access to only one pH buffer, you can always perform the calibration in at least one point. Both meters also feature a user-selectable automatic shut-off to save battery life.
The ABS housing provides the instrument with optimum protection from harmful environments.
A dual level LCD displays pH (or mV) and temperature at the same time. Graphic symbols guide the user through the calibration process.
To ensure your subsequent measurements are accurate, these meters will only allow calibration when the electrode has stabilized.
These meters are supplied complete with BS4 72-1948 double-junction pH electrode with BNC and 1 m (3.3 ft) cable, BS4 72-1949 temperature probe with 1 m (3.3 ft) cable, 4 x 1.5 V AA batteries, pH 4 and 7 buffers in a rugged case.
