SGT-D NH3 – Maintenance-Free Ammonia Gas Detector

SENKO SGT-D NH₃ – Maintenance-Free Ammonia (NH₃) Gas Detector

The SENKO SGT-D NH₃ is a portable single-gas detector designed for continuous measurement of ammonia (NH₃) in the ambient air. The model is maintenance-free (disposable) and operates for up to 24 months without the need to replace the battery or sensor. After initial activation, the device begins continuous measurement and operates until the built-in battery is depleted.

The detector is suitable for use in industrial facilities, production plants, underground facilities, power generation, and other environments where there is a risk of ammonia accumulation.

Advantages:

• Fast sensor response;
• Compact;
• 360° alarm, including:
  • a powerful 90 dB siren;
  • strong vibration;
  • bright red LED indicator;
• Maintenance-free.

Key Features

• Gas measured: ammonia (NH₃)

• Measurement range: 0–100 ppm

• Service life: up to 24 months

• Sensor type: electrochemical

• Memory: up to 30 alarm events

• Protection rating: IP66 / IP67

• Operating temperature: -40°C to +50°C

Reliable detection and fast response

The detector is equipped with a highly sensitive sensor with a fast response time. When hazardous concentrations are reached, a two-stage alarm is activated:

• First level: above 25 ppm

• Second level: above 35 ppm

The display shows the current concentration and the activated alarm level.

The Senko SGT-D can be configured via the optional IR module, which allows you to change the alarm levels and download data from the device’s memory.

Easy to use

The Senko SGT-D NH₃ operates with a single button. The monochrome liquid crystal display shows all the necessary information. The LCD display shows:

• current NH₃ concentration

• alarm level

• unit of measurement

• remaining service life indicator

Small and easy to carry

The Senko SGT-D is compact—smaller than a cigarette pack. It weighs only 93 g, making it lighter than most other similar detectors on the market. It features a clip on the back for attaching to clothing or a bag.

Event Logger for Analysis and Reporting

The Senko SGT-D gas detector stores records of the last 30 alarms and the measured peak gas concentrations.
