Labtron ORP Tester is specialized to measure -999 to 999 mV oxidation-reduction potential of solution. They consist of probe, which contains platinum sensor that responds to the redox reactions in the solution. Their extended battery life supports prolonged usage in remote locations without the need for frequent recharges. They include data logging capabilities, allowing users to monitor changes and trends over time. Our ORP Tester is suitable for water treatment, aquaculture, and food processing.


Labtron Pocket ORP tester is designed to measure samples with both strong and weak redox potential. It is useful in applications like monitoring chromate reduction, cyanide oxidation, and redox reactions in swimming pools, aquaculture systems, and drinking water. The device can handle different types of samples, making it suitable for water testing. Our tester's versatility allows it to be used in both industrial and environmental testing scenarios.
The Pocket ORP tester's auto hold function automatically locks the stable reading on the display once it detects consistent measurements. This eliminates the need to monitor the screen constantly and helps ensure you capture the most accurate value. It is useful when working in environments where quick and precise recording is important. The feature enhances usability and minimizes human error during data collection.
Our Pocket ORP tester is compact and lightweight, weighing just 100 grams and measuring 175 mm in length. It offers a waterproof design that ensures durability in wet or harsh outdoor conditions, making it reliable for on-site testing. With a long battery life of up to 200 hours using standard AAA batteries, it is built for extended use in the field. The rugged build and portable design make it a dependable tool for environmental and industrial fieldwork.
Labtron's Pocket ORP tester supports one-point offset calibration in relative mV mode, which allows you to match the meter’s readings to a known standard solution. This is particularly helpful when you need to fine-tune accuracy for specific testing conditions. Calibration ensures consistent and reliable results over time, especially in professional or regulatory testing environments. The process is straightforward and quick, making regular maintenance easy for the user.
Our Pocket ORP tester features an automatic power-off function that activates 8 minutes after the last button press to prevent unnecessary battery drain. This is especially helpful if you forget to turn off the device manually after testing. Additionally, the reset function lets you restore factory settings quickly, which is useful if the device has been misconfigured. These features help extend battery life and maintain operational efficiency.
