They operate using electrodes (ISEs), which respond selectively to particular charged species, allowing for accurate and reliable measurements. Their built-in temperature sensors allow for automatic adjustments to readings minimizing interference from surrounding environmental factors. They feature user-friendly interfaces for easy navigation through evaluation settings and calibration processes. Our Benchtop Ion Meter is essential in environmental monitoring, food and beverage analysis, and pharmaceutical research.








Labtron Benchtop Ion meter for NH3 is ideal for monitoring ammonia ion concentrations in potable water, distilled water, wastewater, and natural water bodies. It is particularly useful in wastewater treatment plants, aquaculture facilities, and environmental testing labs where ammonia presence can affect safety and compliance. The meter's detection range from 0.02 to 17000 ppm allows it to handle trace-level to high-concentration scenarios. This versatility supports both regulatory compliance and process optimization.
The Benchtop Ion meter for NH3 includes automatic and manual temperature compensation over a wide range (0–100 °C), which adjusts readings for temperature-induced fluctuations in ion activity. This feature is critical in outdoor or industrial environments where sample temperatures may vary. Users can rely on stable results with a temperature accuracy of ±0.5 °C and resolution of 0.1°C even under changing conditions. This ensures dependable monitoring regardless of where the sample is collected.
Yes, Our Benchtop Ion meter for NH3 is designed to feature a large LCD and a system menu that allows configuration of up to 8 key parameters. Direct ion concentration readouts in ppm, mg/L, or mol/L simplify interpretation for less experienced users. Calibration is at 2 to 5 points with commonly available standard solutions. New users can achieve accurate, repeatable results with built-in features like auto hold.
Labtron's Benchtop Ion meter for NH3 comes with built-in memory to store up to 500 data sets, each tagged with a real-time clock stamp for traceability. It also includes a USB communication interface for quick data transfer to a PC, making it easier to archive and report results. These features are useful for regulatory documentation, research logging, and long-term trend analysis. The ability to export data supports efficient lab workflow and digital recordkeeping.
Our Benchtop Ion meter for NH3 includes auto power-off settings (10, 20, or 30 minutes), helping to preserve energy and prolong device life. The auto-hold features stabilize readings before they are logged, reducing the risk of recording inaccurate data. The robust LCD display and durable housing make it suitable for busy lab environments. These safety measures ensure consistency and reduce the risk of human error during testing.
The Benchtop Ion meter for NH3 requires regular calibration using the supplied standard solutions and adheres to the calibration due reminders. It is important to clean and store the ammonia ion-selective electrode properly after each use to avoid contamination or membrane damage. The temperature probe and USB interface should be checked and cleaned properly to help maintain performance. Periodic use of the reset function can restore factory settings if any operational inconsistencies occur.
