About DTekGaz
DTekGaz is an industrial gas detection equipment manufacturer supplying fixed and portable monitoring systems for hazardous and toxic gas environments. The product portfolio spans catalytic and semiconductor sensor probes, control modules, audible alarm units, batteries, and extension cards designed for deployment in petrochemical plants, refrigeration systems, hazardous areas, and industrial process monitoring. DTekGaz probes are available in multiple sensor types—catalytic sensors for explosive gas detection, semiconductor sensors for refrigerant monitoring (R407C, R410A, R32, R134a, R404A, 507), and electrochemical variants for specific gas families. Many models carry ATEX EX II2 GD certification for use in Group II explosive atmospheres, meeting EN standards for safety-critical applications. IP ratings across the range span IP54 to IP65, accommodating indoor control rooms and outdoor or wet-environment installations. Probes feature microprocessor control with automatic calibration and diagnostic functions, reducing maintenance intervals and field recalibration costs. Detection thresholds are configurable; extension card modules trigger pre-alarm at 13% LEL and main alarm at 20% LEL, with three relay outputs for fault, pre-alarm, and general alarm signaling. Power supplies include rechargeable 12 V DC batteries (6 Ah capacity, 17% self-discharge after 6 months) and 24 VDC operation for fixed installations. Audible alarm units deliver 100 dB sound output with integrated flashlight indicators. 3G Electric maintains a 94-SKU inventory of DTekGaz equipment, supporting plant engineers and maintenance teams across Southeast Asia and global markets with same-day order fulfillment and technical specification support.

Frequently asked questions
Common questions about DTekGaz from 3G Electric.
What ATEX certification does the DTekGaz SG895 probe carry, and which gases does it detect?
The DTekGaz SG895 is certified ATEX EX II2 GD, qualifying for Group II explosive atmospheres. It uses a catalytic sensor with microprocessor control to detect both explosive and toxic gases in hazardous industrial environments. The probe includes auto-calibration and auto-diagnostics functions to maintain accuracy without frequent manual recalibration.
What is the measurement range and sensor type of the DTekGaz HCF100 refrigerant gas probe?
The DTekGaz HCF100 employs a semiconductor sensor with automatic calibration and measures refrigerant gases including R134a, R404A, R407C, R410A, R32, and 507 up to 999 ppm. It is rated IP55 and housed in self-extinguishing polypropylene per VDE 0471, suitable for refrigeration service areas and HVAC equipment rooms.
How do the DTekGaz extension card relay outputs function in a gas detection system?
The DTekGaz extension card outputs a 4-20 mA linear signal and controls three independent relays: one for fault detection, one for pre-alarm (triggered at 13% LEL), and one for general alarm (at 20% LEL). This three-relay architecture enables parallel signaling to multiple devices—audible alarms, shutdowns, or remote notifications—without a separate PLC. The card is compatible with SGM595 and SG895 probes and meets EN50270 EMC standards.
What battery specifications should I use for portable DTekGaz gas detection equipment?
DTekGaz supplies a 12 V DC rechargeable battery (model AC200, 6 Ah capacity) with AMP faston tipo 187 terminals for field-portable detection units. It exhibits a low self-discharge rate of 17% after 6 months, minimizing downtime between field deployments. This battery integrates directly into handheld probes and temporary monitoring setups.
What sound pressure level does the DTekGaz audible alarm unit produce?
The DTekGaz audible alarm with integrated flashlight generates 100 dB sound pressure at 100 cm distance, meeting industrial audibility requirements in noisy plant environments. It operates at 24 VDC with 1 W power consumption, features a 3-minute timer with manual switch control, carries a 3-year warranty, and is rated IP54 for light moisture exposure.
Which metal-housed DTekGaz probes are available for flammable gas detection?
DTekGaz supplies butane and hydrogen detection probes in metal housing with IP65 protection (SKU DTK12019 and DTK12022). Metal enclosures prevent electromagnetic interference in electrically noisy plant areas and withstand mechanical shock in congested equipment rooms or outdoor installations where plastic housings may degrade.
