| | | This instrument is light, functional and very robust. It has been designed to work in harsh conditions, both in industry and in the field or lab. Two instruments in one. Depending on the sensor connected, it can be a Key features Double-LCD display screen, for simultaneous readings of pH, or mV and temperature. With icons indicating battery, calibration, unit, etc. status. Two instruments in one: a pH- meter and a thermometer. As a pH-meter it measures pH and °C and, by replacing the pH electrode with a temperature probe with a Ft 1000 sensor, itturns into a precision thermometer for up to 600 °C. The temperature probes which can be connected to the PH 25 are described on pages 44 and 98. | | Automatic calibration with 1, 2 or 3 buffers, which can be pH 2.00, 4.01,7.00,9.21 and 10.90,values at25°C. Error messages for incorrect calibrations. The instrument automatically switches itself off if no keys are pressed for 5 minutes. This function can be disabled bythe user. Uses very little electricity. With the instrument on, the batteries will last approximately 1000 hours. IP 65 Protection. Dust- and waterproof. Sensors connector (IP 67 protection) for connecting pH electrodes with or without an integrated temperature sensor. Any Pt 1000 temperature probe can also be connected to it. | | "Long life" membrane keypad, guaranteed for up to 6 million strokes per key. Optional carry-case, holds everything you need to work in comfort. Advantages of the PH 25 • Very easy... • Shock-resistant • Ergonomic design • Long-life batteries • Industrial-use keypad • Very competitively priced Limitations All portable instruments, even watertight ones, are at risk from condensation when exposed to low temperatures. This limitation disappears when using CRISON lab or process pH-meters. Certificates Supplied with the EC Declaration of Conformity as per directive EMC 89/336/EC, and specifications certificate.
