Professional FAQs
What is the typical T90 response time?
The analyzer responds in under 6 seconds at standard flow rates.
How often should the unit be calibrated?
Calibration is typically needed every 6–12 months.
Can it operate in high humidity sites?
Yes. It works from 0–95% RH as long as moisture does not condense.
What output formats does the analyzer support?
It supports 0–20 mA, 4–20 mA, and RS485 communication.
Is the analyzer suitable for outdoor installation?
Yes. The IP66 / NEMA 4X rating allows use in outdoor and washdown areas.
