Pocket ORP Tester LPOT-A10 : Platinum sensorLabtron 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 ideal for measuring oxidation-reduction potential (ORP) in various industries. It is commonly used in swimming pool water testing, aquaculture, and drinking water analysis. The tester helps monitor redox reactions in processes such as chromate reduction, cyanide oxidation, and other chemical reactions that require precise ORP measurement. Its versatility makes it suitable for both industrial and environmental applications.
The Pocket ORP tester offers excellent accuracy with a tolerance of ±2 mV across its full range of -999 to 999 mV. This ensures reliable measurements in both highly controlled and variable environments. Users can obtain fine-grained insights into the ORP levels of their samples with a resolution of 1 mV. This precision is crucial for processes where ORP is an indicator of chemical balance, such as water treatment.
Our Pocket ORP tester is designed for simplicity, featuring a compact and lightweight design that makes it easy to carry and handle in the field. It offers LCD screen displays results clearly. The auto-hold function freezes stable readings, which is useful for accurate recording in dynamic environments. The 1-point offset calibration is straightforward, ensuring quick adjustments to maintain measurement accuracy without complicated setups.
Yes, Labtron's Pocket ORP tester is built with waterproof features, making it resistant to splashes and submersion in harsh conditions. This makes it perfect for field use in environments like swimming pools or aquaculture tanks, where exposure to water and chemicals is common. The platinum sensor is durable in nature. This ensures reliable performance even under challenging environmental conditions.
The Pocket ORP tester runs on two 1.5V AAA batteries. It offers a long battery life of approximately 200 hours. To help conserve battery power, it features an automatic power-off function that activates after 8 minutes of inactivity. This feature is ideal for saving energy during extended periods of non-use, especially when working on long testing sessions.
