Product Description P/N: MIDAS-T-004
Description
The Honeywell Analytics MIDAS-T-004 is a single-zone ammonia gas monitor designed for continuous detection of NH₃ concentrations from 9 to 100 ppm. Operating on 24 VDC, it uses single-pass infrared non-dispersive sensing technology to provide accurate measurement and stable performance. The MIDAS-T-004 supports remote sampling up to 100 ft and integrates with control systems via relay outputs, 4–20 mA signal, and Modbus/TCP communication.

Information About MIDAS-T-004
The MIDAS-T-004 is a fixed gas detection module engineered for monitoring ammonia in industrial and commercial environments. It features a single-pass NDIR sensor for selective gas detection with ±2% linearity and ±5% repeatability across its measurement range. The unit includes three configurable alarm relays, a system fault relay, and a 4–20 mA analog output for integration with building management or safety systems. Designed for single-point monitoring, it includes a 10 ft sampling and exhaust tube and supports extended sampling distances up to 100 ft.
Key Features:
- Ammonia Detection (NH₃): Monitors concentrations from 9–100 ppm using NDIR technology.
- Single-Pass Infrared Sensor: Provides stable and selective gas measurement.
- Multiple Alarm Outputs: Three alarm relays (1A @ 30 VDC / 0.5A @ 125 VAC) plus fault relay.
- 4–20 mA Output: Enables integration with PLCs and building management systems.
- Modbus/TCP Communication: Supports network-based monitoring and diagnostics.
- Digital Display: 4-digit screen for real-time and peak gas level indication.
- Remote Sampling Capability: 10 ft tube included; supports up to 100 ft sampling distance.
- Visual Alarm Indication: Provides local visual notification of alarm conditions.
The MIDAS-T-004 delivers the reliability and precision required for fixed ammonia gas detection and safety monitoring systems.
