Hytera PT790Ex intrinsically safe two-way radio

Hytera has released the PT790Ex, an intrinsically safe two-way radio that also complies with the highest explosion-proof standard ‘ia’. This device has passed ATEX, FM, IECEX certifications and complies with IP67 rating as well as MILSTD 810 C/D/E.

The two-way TETRA radio is operable in places that contain explosive gases, including mine methane, such as coalmines, gas stations, oil platforms, chemical plants, airports and other inflammable or explosive conditions. It can also be used in Zone 0/1/2 and complies with M1.

The rugged device features an antistatic shell made of light metal to avoid mechanical spark and reduce the possibility of static discharge. The 1.8″ LCD screen is also crack-proof and provides users a clear display even under bright sunlight. Separated by the antenna, the radio’s channel knob and volume knob stand apart from each other, while large textured keys provide good tactile feeling. These features combined are designed to help offer ease of use and accuracy when users wear gloves or operate the device in dark environments.

The product supports GNSS positioning, man down and lone worker functions for worker safety. It also provides a 1800/2400 mAh large capacity Li-ion battery, which lasts over 20 h under 5-5-90 duty cycle. A strict overcharge and over-discharge protection design ensures the battery against instability caused by overheating.
