Product Introduction

The QH-101 BOD analyzer is designed according to the national standard "HJ505-2009 Determination of Five day Biochemical Oxygen Demand (BOD5) in Water Quality - Dilution and Inoculation Method". It simulates the biodegradation process of organic matter in nature and uses a simple, safe, and reliable mercury free pressure difference sensing method to measure the BOD value of water quality. The instrument adopts intelligent measurement and control technology, and the entire measurement process is controlled and viewed through a mobile APP, with wireless data transmission. It can automatically reconnect and match multiple sets of devices, making it convenient to view the measurement data results in real time. It can be widely applied to environmental monitoring stations, third-party testing institutions, scientific research, universities, and sewage discharge enterprises.

Features

1. Wireless data transmission, mobile app control, and graphic display throughout the entire operation process;

2. Industrial appearance mold design, compact overall size,;

3. Adopting innovative sensing technology to effectively avoid the influence of external atmospheric pressure changes on measurement results;
