I. Product Introduction

The biochemical oxygen demand (BOD) analyzer is based on the national standard HJ505-2009 5-day culture method and simulates the biological degradation process of organic matter in nature. It uses a simple, safe and reliable mercury-free pressure difference sensing method to measure the BOD concentration in water. With a fully intelligent design and leading R&D technology and manufacturing, the experimental process requires no operator attendance. It is suitable for BOD determination in pollutant-discharging enterprises, environmental monitoring, wastewater treatment plants, third-party testing institutions, scientific research and universities.

II. Key Features

1Android system, with a better interactive operating experience, simpler and faster.
27-inch LCD touch screen with a convenient operation interface; all values are displayed for comparison, intuitive and clear.
3Adopts the internationally advanced mercury-free pressure difference method, with no mercury pollution and accurate, reliable data.
46 test terminals, independently controlled; new measurement groups can be added at any time during testing.
5The test terminals connect to the main unit via Bluetooth and wirelessly transmit data to the host display.
6No manual conversion is required; the instrument directly displays the BOD concentration value, and multiple data sets can be displayed on a single interface.
7The instrument can automatically analyze and plot the data curves of measured water samples, and multiple curves can be displayed on a single interface.
8Each test terminal has a built-in large-capacity lithium battery with a service life of more than 2 years; a brief power outage has no effect on testing.
9The base integrates 6 USB ports that can be used directly to charge the test terminals; a full charge can last more than half a year of use.
10No piping design in the experimental section, avoiding problems such as pipe aging and air leakage.
11Selectable measurement range; no dilution is required when the water sample concentration is below 4,000 mg/L.
12The analyzer automatically records measurement data, and the time-recording frequency can be set arbitrarily for more precise data.
13The culture time can be flexibly adjusted according to requirements, up to 30 days.
14Automatically completes the measurement process without dedicated attendance.
15Built-in thermal printer that can automatically print the parameters set before measurement, and unwanted print content can be freely cancelled.
16Built-in clock system that displays the time in real time and allows measurement data to be queried by time.
17The instrument is equipped with a cloud platform; detection data can be uploaded wirelessly via WIFI and viewed, counted and analyzed on a computer or mobile phone with greater clarity.
18The instrument has a built-in operation-step demonstration video, so users can learn by watching the video inside the instrument and get started faster.
