GTD-5000 suction-type gas detector

GTD-5000 Suction-Type Gas Detector

Non-explosion-proof pump-suction gas detector with a high-performance diaphragm pump for fast sampling of the target space. Detects combustible, toxic, Freon, oxygen and VOC gases; 4-digit LCD readout, 4-20 mA, RS-485 Modbus and PoE communication, relay contact output, and a cartridge-type sensor for easy field replacement and maintenance.

  • Pump suction
  • Combustible / toxic / O2 / VOC
  • 4-20 mA / RS-485 / PoE
GTD-5000 Portable gas detector

GTD-5000 Portable Gas Detector

A handheld interference-gas filtering detector with an NDIR infrared sensor and anti-interference algorithm for continuous detection of combustible, Freon, toxic and precursor gases. Built-in high-performance pump with flow control and a sampling probe for real-time checks in hard-to-reach spots. Rechargeable via USB Type-C (PD 3.0) with over 15 hours of continuous operation, plus self-diagnostics.

  • Portable surveying
  • NDIR principle
  • 15 h+ battery life
GTD-2000Tx diffusion-type gas detector

GTD-2000Tx Diffusion-Type Gas Detector

Smart diffusion-type detector dedicated to oxygen and toxic gases, with a flameproof enclosure that removes the risk of secondary explosion. A built-in display makes status checks and calibration easy on site; HART communication is supported and calibration / parameter setting can be done remotely with a magnetic bar — simple enough for a single technician. It also interlocks with the detector-mounted explosion-proof warning light GTL-100. Standard 4-20 mA output, LCD display (OLED optional).

  • Diffusion / flameproof
  • O2 / toxic gases
  • HART magnetic-bar calibration
GTD-5000F fixed gas detector

GTD-5000F Fixed Gas Detector

Fixed-installation gas detector with a flameproof enclosure suited to harsh industrial conditions. A high-brightness LED readout shows the gas concentration directly on site, and the detector interlocks with alarm controllers and warning lights — ideal for pump rooms, tank farm areas and specialty-gas cabinets that require continuous monitoring.

  • Fixed installation
  • LED readout
  • Flameproof enclosure
GTD-6000 combination gas detector

GTD-6000 Combination Gas Detector

Combination (COMBI) gas detector that monitors multiple gases with a single unit. A high-brightness LED readout stays visible from a distance, with built-in alarm relay outputs and audible / visual indication that interlock with central monitoring systems — well suited to gas rooms and laboratories where several gases must be monitored together.

  • Multi-gas combined
  • LED readout
  • Audible & visual alarm
GTM series suction-type multi-gas detector

GTM Suction-Type Multi-Gas Detector

One unit monitors four or more gas channels simultaneously — combustible, toxic, Freon and VOC gases — with sensor combinations (infrared / catalytic / electrochemical) configured per site. A color graphic LCD shows all channels at a glance; 4-20 mA analog outputs plus RS-485 Modbus / PoE (option) and 3 SPST relay contacts make it ideal for specialty-gas rooms and analyser shelters.

  • 4+ channels
  • Configurable sensors
  • PoE option
GPD-100 cartridge-type portable gas detector

GPD-100 Cartridge-Type Portable Detector

Cartridge-type pump-suction portable detector for combustible, toxic, oxygen and VOC gases. A high-performance diaphragm pump samples the target space quickly, and the detachable sensor cartridge makes field maintenance simple. A color LCD shows concentration and status, and a full charge keeps it running for about 10 hours.

  • Cartridge sensor
  • Pump suction
  • About 10 h battery
GTC-540A single-channel gas alarm controller

GTC-540A Single-Channel Alarm Controller

Wall-mounted single-channel receiver with a 1.8" 4-digit gas concentration display. 3-stage alarm and trouble LEDs, connectable to warning lights. Accepts 4-20 mA (2- or 3-wire) input, provides 4-20 mA output and isolated RS-485 Modbus (option), with built-in self-diagnostics and programmable alarm levels and delay times.

  • 4-digit display
  • 3-stage alarm
  • RS-485 Modbus
GTC-200A multi-channel gas alarm controller

GTC-200A Multi-Channel Alarm Controller

Multi-channel receiver built on the international standard DIN case for easy channel expansion. Each channel provides a 4-digit display with a 32-segment tri-color bar graph; 3-stage alarm LEDs and relay contact outputs, isolated RS-485 Modbus (option) and back-up power (option). Freestanding panel, wall-mounted or 19-inch rack configurations, with built-in self-diagnostics.

  • Multi-channel
  • 19" rack option
  • RS-485 Modbus
GTF-1100U flame detector

GTF-1100U Flame Detector

Point-type flame detector in a compact one-piece design with fast flame response and good false-alarm immunity, interlocking with alarm controllers and warning lights — suitable for tank farm areas, loading areas and pump rooms that require flame monitoring.

  • Point detection
  • Fast response
  • Compact design
GIR-3000 gas detector

GIR-3000 Gas Detector

Fixed gas detector with a capacitive gas sensor for O₂ / CO₂ / CO / N₂O and other gases, with local concentration display and self-diagnostics. Supports RS-485 Modbus / HART communication and remote sampling via the GTL-100 subsystem. ATEX / IECEx / KCs / NEPSI certified for chemical and semiconductor process areas.

  • O₂ / CO₂ / CO / N₂O
  • RS-485 · HART
  • ATEX / IECEx
GTD-1000Ex explosion-proof combustible gas detector

GTD-1000Ex Combustible Gas Detector

Explosion-proof combustible gas detector: diffusion type with selectable ranges of 0–100% LEL / 0–2000 ppm / 0–100% Vol, 2-wire 4–20 mA output, FND concentration display and self-diagnostics, interlocking with GTC series controllers. KFI approved — suitable for LNG / LPG stations, boiler rooms and other flammable-gas areas.
