Frequently Asked Questions
Q1: What is the detection principle of the S520 TVOC monitor?
The system utilizes PID (Photoionization Detection) technology, which provides highly accurate and rapid response measurements for Total Volatile Organic Compounds.
Q2: How long is the sensor's service life?
The PID sensor typically has a lifespan of 2 to 3 years under normal operating conditions before requiring replacement.
Q3: Can the monitoring range be customized?
Yes, while standard ranges include 0-200, 2000, or 10000 PPM, other specific ranges can be customized according to your application requirements.
Q4: What types of output signals are available for system integration?
The system supports multiple industrial output signals including 4-20mA analog output, RS485 digital communication, and passive relay contacts for alarm control.
Q5: Is the S520 system suitable for high-humidity environments?
The standard protection level is IP54 for environments up to 90% RH (non-condensing). For higher humidity, an optional pre-treatment system or specialized customization is available.
Q6: How is the device calibrated or debugged?
The system features a remote control debugging method, allowing users to perform functions and display settings without needing to open the unit housing.
