Dissolved Oxygen Tester

Introduction

A conductivity tester measures electrical conductivity of solutions for quality control and analysis. It is widely used in environmental and industrial applications.

Standards

JJF 2294-2025-Calibration specification for on-line low-level dissolved oxygen meters

IEC 60746-4:2018-Expression of performance of electrochemical analyzers-Part 4: Dissolved oxygen in water

Complies with the above standards, but is not limited to them.

Features

1. Dissolved oxygen tester for measuring oxygen levels in water and other liquids.

2. Polarographic oxygen sensor provides accurate dissolved oxygen measurement.

3. Backlit LCD display with automatic temperature compensation for reliable readings.

4. Compact, portable design suitable for laboratory and field use.

5. Suitable for aquaculture, environmental monitoring, wastewater and laboratory applications.

FAQ

Q1: What is the dissolved oxygen tester mainly used for?

A: It is used to measure dissolved oxygen concentration in water, wastewater, aquaculture ponds, rivers and laboratory samples. Dissolved oxygen data supports environmental monitoring, water quality assessment, biological oxygen demand testing and aquarium or aquaculture management.

Q2: What standards does the tester comply with?

A: The instrument is designed with reference to IEC 61010 electrical safety requirements and relevant GB/T standards for water quality testing instruments. Measurement procedures should follow applicable water quality standard methods. Compliance documentation can be provided on request.

Q3: What is the warranty period for the tester and key components?

A: The complete unit carries a 12-month warranty covering the meter body and electronics. The oxygen sensor membrane, electrolyte and probe are excluded as consumables. Damage from improper handling or unauthorised repair is not covered.

Q4: Is the tester difficult to operate?

A: Operation is simple: calibrate the sensor, immerse the probe and read the display. Basic training in sensor care and calibration is recommended. The manual explains calibration, measurement and maintenance, and remote guidance is available.

Q5: What is the typical lead time for order delivery?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Does the tester require calibration or verification?

A: The sensor should be calibrated before use and verified periodically against reference solutions or saturated water, typically weekly or monthly depending on use. The meter is factory tested before delivery. Optional calibration service can be arranged.

Q7: Are consumables or spare parts universal?

A:Sensor membranes, electrolyte and replacement probes are standard consumables available through our channel and are compatible with common dissolved oxygen sensors. No proprietary locked parts are required. Quote the model and serial number when ordering.

Q8: Can the tester be customised?

A: Options include different cable lengths, probe types, data logging and calibration certificates. We confirm each option before order confirmation.

Q9: Is installation or setup required?

A: No installation is required; the tester is ready to use after battery installation and calibration per the manual. Remote guidance is available for first-time calibration.

Q10: What samples should not be measured with this tester?

A:Strong solvents, aggressive chemicals and very high-temperature liquids may damage the membrane or sensor. Samples must be compatible with the polarographic probe. Follow laboratory safety regulations.
