Description
The MW150 Max Benchtop pH/ORP/Temperature Meter is a high-performance, microprocessor-based lab instrument designed for users who require fast, reliable, and professional-grade measurements. Built for durability and precision, it is an essential tool for laboratories in water treatment, food and beverage, and environmental testing.
Key Features & Benefits
1. Professional Accuracy & Range
The MW150 provides high-resolution readings across three critical parameters:
-
pH Range: -2.00 to 16.00 pH
-
ORP Range: ±699.9 mV; ±1999 mV
-
Temperature Range: -20.0 to 120.0°C (-4.0 to 248.0°F)
2. 3-Point Calibration
Ensure the highest level of accuracy with an easy-to-use calibration process. The meter allows for up to 3-point automatic calibration with 7 standard memorized buffers, reducing manual errors and ensuring consistency across different testing environments.
3. Automatic Temperature Compensation (ATC)
Fluctuations in temperature can affect pH readings. The MW150 features Automatic Temperature Compensation, ensuring that your data remains accurate regardless of the sample’s thermal state.
4. Large, Easy-to-Read LCD
The built-in dual-level LCD displays both the primary measurement (pH or ORP) and the temperature simultaneously. It also features helpful graphic symbols and messages to guide the user through calibration and operation.
5. Robust Design for Lab Use
The benchtop design is stable and space-efficient. It comes equipped with a MA917B/1 double junction glass pH electrode and a stainless steel temperature probe, ensuring longevity even in demanding chemical environments.
