| Field Waterproof pH Meters |
| Models HI9024C and HI9025C |
HI9024 and HI9025 are microprocessor-based pH meters in waterproof casings. HI9024 measures pH and °C, and HI9025 can also measure 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 miroprocessor 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 hwne the electrode has stabilized. The powerful software of the HI9024/HI9025 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. |
| FEATURES |
| READY function |
| To ensure your subsequent measurements are accurate, these meters will only allow calibratioon when the electrode has stabilized. |
| Rugged, waterproof construction |
| The ABS housing provides the instrument with optimum protection from harmful environments. |
| Dual level display with graphic symbols |
| A dual level LCD displays pH (or mV) and temperature at the same time. Graphic symbols guide the user through the calibration process. |
