Pen type pH meter SK-662PH 1 piece

This pen-type pH meter complies with the waterproof standard JIS C0920 IPX5, so it can be operated even with wet hands. The sensor is replaceable. Equipped with 3-point calibration function, display freeze HOLD, auto power off, stable display function, automatic temperature compensation (ATC) function, and sensor sensitivity display function (you can check the deterioration state of the sensor and clearly understand the maintenance and replacement time of the sensor) *pH standard solution is sold separately (optional). pH standard solution is required for accurate pH measurement. Calibration is possible at 1 to 3 points, and the optimal point (at 25°C) can be selected from pH 4.01, 6.86, 9.18, or 10.01. Measurement range: 0.0 to 14.0 pH, 0.0 to 50.0°C Resolution: Temperature/0.1℃, pH/0.01pH Measurement accuracy: ±0.05 pH, ±0.5 °C Sensor: pH/glass electrode Internal solution (KCl): non-refillable, temperature/thermistor Material: ABS resin Dimensions and weight: φ38×(l)171mm approx. 82g (including batteries) Power supply: 4 x IR44 button batteries Accessories: 4 IR44 button batteries, hand strap Code number: 6430-00 Consumables: Replacement sensor No. 6431-00 660S CD: 61-0066-38 *Standard solutions are required separately. Depending on the substance being measured, such as organic solvents, oils, strong acids, strong alkalis, and surfactants, the glass electrode may deteriorate and its lifespan may be significantly shortened.
