Portable single-parameter water quality detector AMT-DO100 - AMT-DO100

Definition: A handheld/portable instrument specifically designed to measure only one water quality parameter, divided into electrode type (pen-type/handheld probe) and spectrophotometric colorimetric type, with simple structure, strong specificity, and lower price compared to multi-parameter instruments.

Product Model: AMT-DO100

Product Introduction

Portable single-parameter water quality detector  AMT-DO100

Definition: specifically measures onlyone water quality parameterhandheld / Portable instrument, divided intoElectrode type (pen-type / Handheld probe)andSpectrophotometric colorimetric type, simple structure, strong specificity, lower price than multi-parameter.

1. Two major types & Common models

1. Electrochemical electrode type (mainly pen-type, no reagents, measure by immersion)

Principle: electrode sensing, automatic temperature compensation

  • pH meter: measures acidity and alkalinity, most common pen-type
  • DO Dissolved oxygen meter: dissolved oxygen in water, aquaculture, rivers
  • ORP ORP meter
  • Conductivity / TDS Pen: measures total dissolved solids, mineralization
  • Salinity meter ✅Advantages: After calibration, directly immerse in water to read, results in seconds; very small, pen-shaped; no consumables.⚠️Disadvantages: Electrodes age, require regular calibration and immersion storage; cannot measureCODchemical pollutants such as ammonia nitrogen.

2. Spectrophotometric colorimetric single-parameter detector (host + pre-packaged reagents)

Principle: water sample plus reagent develops color,LED measures absorbance to convert concentration Common:Single-parameter residual chlorine detector, ammonia nitrogen detector,COD detector, total phosphorus, turbidity, hexavalent chromiumetc. ✅Advantages: Good accuracy for a single parameter, suitable for on-site rapid screening; ⚠️Disadvantages:Must use dedicated reagents, reagents have a shelf life;COD and total phosphorus require on-site digestion for some models.

2. Core advantages and disadvantages

👍Advantages

  1. Strong specificity, optimized for a single parameter, good stability
  2. Lower price, simple maintenance; buy one for whichever parameter is needed
  3. Small size, light weight, battery-powered, convenient for field and inspection carrying
  4. Low operating threshold, suitable for long-term fixed monitoring of a single parameter

👎Disadvantages

  1. Can only measureone parameterIf multiple parameters need to be measured, multiple instruments must be purchased
  2. Electrode type: Electrodes are consumables, lifespan generally 1~3 years, requires regular calibration
  3. Spectrophotometric type: continuously consumes pre-packaged reagents, long-term use has consumable costs

3. Typical application scenarios

  • Swimming pool / Secondary water supply:Single-parameter residual chlorine meter
  • Aquaculture:Dissolved oxygen meter,pH Pen
  • Pure water / RO water outlet:TDS Pen
  • River patrol only measures turbidity:Portable turbidity meter
  • On-site wastewater screening only for ammonia nitrogen / COD: single-parameter spectrophotometric detector

Main Application Areas

  • Industrial Water Monitoring — Continuous or periodic monitoring of specific water quality parameters in industrial processes to ensure compliance and process efficiency.
  • Environmental Field Testing — On-site measurement of water quality in rivers, lakes, and wastewater for environmental assessment and regulatory compliance.
  • Aquaculture Management — Monitoring dissolved oxygen and other critical parameters in fish farms and aquaculture systems to maintain healthy aquatic life.
  • Drinking Water Safety — Rapid testing of drinking water sources and distribution systems to ensure safety and quality standards are met.
  • Laboratory & Research — Portable and convenient measurement of single parameters in laboratory experiments and field research studies.
