Hytera’s PD79X Ex DMR hand portable radio has received more intrinsically safe certifications in various global markets making it one the most completely certified IS DMR radios on the market, according to the company. The certifications include ATEX, CSA, CQST, FM and IECEx, among which the CQST, a Chinese IS directive, was obtained at the end of 2011.
In hazardous environments where the presence of a tiny spark, heat or flame could create a huge hazard, two-way radio communication systems must be compliant with stringent national and international directives. The PD79X Ex is designed to be used in hazardous areas where safety is highly critical such as in oil refineries, fuel storages, drilling platforms, gas fields, mining activities and the like.
The PD79X meets the strict requirements of European ATEX and North American FM standards. With certifications for ATEX, IECEX, the latest FM and CSA specifications, the radio works safely in most hazardous environments even with the presence of hydrogen and dust particles.
The overall design also complies with the latest American Military Standard-MIL-STD-810G, which makes it can bear the harshest environments like high/low temperature, high humidity, vibration and shock.
Other safety featurs incude a dedicated emergency button. In case of any accident, a press on the button will trigger an alarm and initiate a voice call to a pre-programmed work fellow or group. Built-in man-down, GPS and lone worker functions are also available with the digital portable.
Hytera PD79X Ex comes with a high-capacity Li-Ion battery of 1800mAh with long shift life of 17 hours under 5-5-90 duty cycle. The battery charging and discharging circuits are stringently designed to prevent overcharging or discharging causing high heat, which leads to unstable battery environments. In addition, the battery cells are also encapsulated to redistribute single point heat buildup and also prevent air discharge.
The radio also harnesses the benefits of DMR digital technology by providing higher audio quality and stable communication performance with 40% less battery consumption than analogue radios. It provides better communication quality and enhanced privacy, and moreover reduces overall equipment costs, Hytera said.
Hytera PD79X Ex is very easy to use. It provides tough and highly readable LCD screen and intuitive user interface. The anti-skidding and fool-proofing ergonomic designs are designed for easy user operation. Large PPT button and channel knobs are equally useful for users wearing gloves.
