Timbangan Ohaus AB33M1-B AQUASEARCHER Multi

Timbangan Ohaus AB33M1-B AQUASEARCHER Multi

The Timbangan Ohaus AB33M1-B AQUASEARCHER Multi  is a versatile benchtop instrument engineered for simultaneous measurement of pH, mV (ORP), and conductivity. Designed for professional laboratories and research facilities, this meter ensures high accuracy, wide measurement capability, and easy operation. It is ideal for users who require a single, reliable device for both electrochemical and conductivity testing.

Features

The AB33M1-B provides an extensive measuring range—from -2.00 to 20.00 pH, -2000.00 to +2000.00 mV, and 0.01 μS/cm to 500 mS/cm—allowing it to handle various analytical tasks across chemical, environmental, and educational laboratories. In addition, it delivers outstanding precision with an accuracy of ±0.01 pH, ±0.5 mV, and ±0.3°C, making it suitable for both routine measurements and advanced research applications.

The meter features an LCD with backlight and one-line dot-matrix display, which presents data clearly even in low-light environments. Its intuitive interface allows quick access to calibration settings, parameter switching, and measurement recording, thus improving laboratory efficiency. Although the electrode is not included, the AB33M1-B is compatible with a wide range of Ohaus pH and conductivity electrodes, offering flexibility for different sample types and measurement needs.

Moreover, the instrument includes automatic temperature compensation (ATC) when connected to a compatible temperature probe, ensuring consistent accuracy under fluctuating thermal conditions. Because of its compact and ergonomic design—measuring 8.3 × 2 × 5.6 in (210 × 51 × 142 mm) and weighing 1.1 lb (0.5 kg)—it saves valuable workspace while maintaining exceptional performance.
