Van London Chlorophyll a Sensor with Teledyne Connector

Description

Monitoring chlorophyll a levels in water bodies is critical for assessing water quality and environmental health. Chlorophyll a sensors play a crucial role in detecting the presence and concentration of algae, which in turn directly impacts aquatic environments.

AlpHa’s XC-CHLA sensor utilizes patent pending optical technology with the following unique features:

• Industry leading minimum detection limit at 0.01 ppb
• Automatic temperature compensation
• Analog (0 – 3 V) or digital (RS-485 MODBUS RTU) output formats
• Options for custom OEM sonde multiparameter and stand-alone configurations

The measurement of chlorophyll a is essential in environmental monitoring for the following reasons:

• Early detection of algal blooms to prevent harmful ecological effects and ensure public safety
• Evaluating water quality to assess nutrient pollution levels and manage ecosystems
• Supporting environmental compliance with water quality regulations
• Helping to design and implement sustainable water management practice
   

Environmental monitoring applications often measure chlorophyll a in real time using on-site sensors or laboratory analysis of grab samples. Typical chlorophyll a levels in natural waters vary widely based on environmental conditions and algal activity.
