 Monitor and troubleshoot HVAC systems,
verify energy management systems, or track performance of pneumatically
controlled valves with Series DL6 Pressure/Temperature/RH Data
Logger. Units include an on-board thermistor for ambient temperature
measurement and pressure module. Remote humidity/temperature
sensor and plug-in humidity sensor are sold separately. Loggers
can store up to 32,768 readings and operate independently from
any external power supply with built-in lithium battery. Use
Model DL200 Windows™ software (sold separately) to quickly
program the logger or upload data to the computer.
