| Brand | ConductScience |
The Waste Water Detection Meter for Total Nitrogen Test (Model LH-D62) is a portable analytical instrument designed for quantitative measurement of total nitrogen content in industrial wastewater samples. This battery-powered field meter enables on-site nitrogen analysis in environments where laboratory access or electrical power is unavailable, supporting environmental monitoring and wastewater treatment compliance workflows.
The instrument provides direct nitrogen concentration measurements using colorimetric detection principles, with results displayed on an integrated digital interface. The compact design (90×70×125mm) and extended battery life (>30 hours continuous operation) make it suitable for field sampling campaigns, effluent monitoring programs, and routine wastewater quality assessments at industrial facilities.
How It Works
The LH-D62 employs colorimetric analysis for total nitrogen determination in aqueous samples. The measurement principle involves chemical conversion of nitrogen-containing compounds to a colored complex that absorbs light at a specific wavelength. Sample preparation typically includes oxidation steps to convert organic nitrogen and ammonia to nitrate, followed by reduction to nitrite for colorimetric detection.
The instrument incorporates photodiode-based optical detection to measure absorbance changes proportional to nitrogen concentration. Internal calibration algorithms convert optical signals to nitrogen concentration values, which are displayed digitally. The portable design integrates sample handling, reagent mixing, optical measurement, and data processing in a single handheld unit.
Battery power enables field operation independent of electrical infrastructure, while the compact optical system provides measurement precision suitable for regulatory monitoring applications. Sample volumes are typically small (consult product datasheet for specific requirements), minimizing sample collection and handling requirements.

Practical Tips
Perform zero calibration with distilled water before each measurement session and verify with certified standard solutions.
Why: Drift compensation ensures measurement accuracy over extended field operations.
Clean sample chamber thoroughly between measurements using distilled water and lint-free wipes.
Why: Prevents cross-contamination between samples that could affect nitrogen concentration accuracy.
Collect samples in clean containers and analyze within recommended holding times to minimize nitrogen compound degradation.
Why: Sample integrity directly affects measurement accuracy and regulatory compliance.
Record sample temperature, collection time, and any visible sample characteristics alongside nitrogen measurements.
Why: Documentation supports data interpretation and troubleshooting of unusual results.
If measurements appear inconsistent, check battery voltage and recalibrate with fresh standard solutions.
Why: Low battery power can affect optical system performance and measurement stability.
Handle reagents according to safety data sheets and dispose of waste samples following environmental regulations.
Why: Chemical reagents may be hazardous and wastewater samples may contain unknown contaminants.
