There are a variety of water quality meters available in the market today. A sensor is the most important component of a water quality meter. There are different types of sensors used in a water quality meter depending on the type of water sample. Below is a list of sensors used in a water quality meter:
- Conductivity Sensor - The open flow design of the conductivity sensor stops air bubbles from interfering with the reading and allows sediments to fall away from the sensor. It is especially designed for easy maintenance with no cell blocks to eliminate or clean.
- Dissolved Oxygen Sensor (Polarographic) – In this sensor, changing DO membranes is simple with snap-on caps which offer uniform stretching for consistent results, and remove any bubbles or wrinkles. A built-in magnetic stirrer preserves consistent flow over the sensor.
- Dissolved Oxygen Sensor (Optical) – This sensor consumes no oxygen, provides a fast response, and requires no stirring. The typical lifespan of this type of sensor is 5 to 10 years. No consumable parts, caps, or membranes are required to be replaced during this time. This sensor is more stable than membrane-covered sensors with a low calibration frequency.
- PH Sensor - You can top off the reference solution without the need to replace the entire sensor with replaceable reference solutions in a glass pH sensor. The sensor lasts for years and the glass pH bulb is easy to clean and hard to break.
- Turbidity Sensor - Turbidity Sensors offer superior linearity. Mathematical algorithms remove sand and particles from turbidity calculations, and the built-in wiper keeps the lens clean.
- Optical Sensors - Self-cleaning optical sensors with integrated wipers eliminate biofouling, preserve high data accuracy and offer improved reliability during extended deployments by detecting chlorophyll a, blue-green algae and rhodamine.
- Ion Specific Sensors – This sensor is sensitive to ammonium, nitrate, chloride and sodium ions. A low-cost and easy to change sensor tip is all that is required when this sensor falls out of calibration.
- Depth and Stage Sensor – A vented digital stage pressure transducer is intended for long-term deployments while a non-vented digital depth sensor is ideal for profiling applications.
GAOTek water quality meters offer a lot of key features helpful in operating the device easily and accurately. Below is a list of key features that GAOTek water quality meters offer:
- Auto-calibration feature provides hassle free calibration of pH, turbidity, dissolved oxygen, conductivity, and depth.
- Shock resistant cover is designed for rough treatment in the field and can be easily cleaned.
- Connecting and disconnecting the cable is easy with quick-connect fitting.
- Auto hold function freezes or locks average data values on the screen to offer more time to verify or transcribe data.
- Diagnostic functions alert the user of errors.
- Integral USB connection allows transfer of data to a PC.
- Selectable measurement units let the operator report data without the need to convert data to desired units of measure.
In addition to all these features, our products have a high precision, high resolution, and high sampling speed. More importantly, our products offer all these features at an affordable price. You can choose from a wide selection of water quality meters at GAOTek.
