Forensics Chlorine Detector — Industrial Wall-Mount (0-20 ppm Cl2, Relay Output)

Forensics Chlorine Detector — Wall-Mount Cl2 Monitor

The Forensics chlorine detector is a wall-mounted, continuously-monitoring Cl2 head reading 0-20 ppm — a fixed gas detection system that drives ventilation or shutdown through its relay output to protect chlorine rooms around the clock.

The Forensics Chlorine Detector is a wall-mounted fixed Cl2 monitor (0-20 ppm) with relay output, explosion-proof enclosure and NIST-traceable calibration for continuous chlorine-room monitoring.

Key features

• Continuously monitors chlorine (Cl2) from 0-20 ppm on a fixed wall-mounted head
• Relay output drives ventilation, alarms or shutdown when Cl2 is detected
• Explosion-proof aluminum enclosure for chlorine rooms and plant areas
• Adjustable sound and light alarms set to your action levels
• USA NIST-traceable calibration
• Always-on Cl2 protection where a carried instrument can't be

Specifications

Where the Forensics Chlorine Detector fits

• Water and wastewater chlorine rooms
• Pool and aquatic plant chemical rooms
• Chemical manufacturing & storage
• Bleach/disinfectant production
• Cl2 cylinder and feed rooms

What the Forensics Chlorine Detector detects (and what it doesn’t)

This head monitors chlorine (Cl2) only — not combustibles, oxygen or other toxics. For combustible monitoring use the Forensics EX LEL Detector; for several atmospheric gases the Forensics 4 Gas Wall-Mount Monitor. For a portable Cl2 survey/exposure tool, pair it with the Forensics Chlorine Analyzer. Mount it low — chlorine is heavier than air — near the source and occupied area, and tie the relay into room exhaust. Recalibrate with Cl2 gas on schedule.

Frequently asked questions

What does the Forensics chlorine detector monitor?

Chlorine (Cl2) from 0-20 ppm, continuously, from a fixed wall-mounted head. It does not detect combustibles, oxygen or other toxics.

Where should a fixed chlorine detector be mounted?

Low on the wall near the source and occupied area — chlorine is heavier than air and settles, so low mounting catches a release.

What is the relay output for?

It triggers ventilation, remote alarms or shutdown when Cl2 reaches the set point — critical for chlorine rooms where leaks must be contained fast.

Is it explosion-proof?

Yes — it uses an explosion-proof aluminum enclosure suitable for plant chemical rooms; confirm the rating against your area classification.

Is it NIST calibrated?

Yes — USA NIST-traceable calibration; recalibrate periodically with chlorine calibration gas to keep readings accurate.

Portable or fixed chlorine detection?

This is the fixed, continuous option for a room. For surveys and personal exposure use the portable Forensics Chlorine Analyzer.

Why is the range only 0-20 ppm?

Chlorine is dangerous at low concentrations, so a low, high-resolution range with low alarm set points is appropriate.

Can it control ventilation?

Yes — that is a primary use of the relay output: energise room exhaust automatically when Cl2 is detected.

Does it detect other gases?

No — Cl2 only. For combustibles use the EX LEL Detector; for CO/H2S/O2/EX the 4 Gas Wall-Mount Monitor.

Is it in stock and how does it ship?

Use the Amazon buy button for current availability and delivery timing through our fulfillment partner.

Does installation need an electrician?

It is hard-wired; installation and relay-to-ventilation wiring should follow local electrical code and area-classification requirements.

How many heads does a chlorine room need?

At least one near each credible release point and the occupied area; larger rooms add heads, often wired to a controller for coordinated response.
