Hytera HP79XEx and PT890Ex intrinsically safe two-way radios

Hytera Communications has released its latest intrinsically safe (IS) radio series, including the HP79XEx DMR portable two-way radio and the PT890Ex TETRA portable radio. Engineered to meet stringent IECEX and ATEX requirements for explosion-proof equipment, the devices enable personnel to efficiently communicate and collaborate with intuitive push-to-talk (PTT) calls at potentially hazardous worksites where explosive gas, combustible dust and chemical vapour exist.

For professionals working in places with a potential risk of explosion such as worksites of oil and gas, mining, chemical and pharmaceutical sectors, the IS performance and reliability of two-way radios is non-negotiable. The HP79XEx and PT890Ex adopt multiple protections such as explosion-proof material and battery, advanced mechanical design and innovative IS circuits to eliminate electrostatic discharges, prevent sparks from accidental drops and provide stable heat dissipation.

The HP79XEx features 2 W RF TX power and 0.16 μV receiving sensitivity, while the PT890Ex offers Class3L TX power level and -120 dBm receiving sensitivity; their high performance enables robust signal transmission and penetration across wide and complex campuses. Their robust 2 W speakers, augmented by AI-based noise cancellation, automatic gain control (AGC) and howling suppression technology, enable loud and clear voice calls in the bustling industrial environment, even at the edge of coverage.

The versatile connectivity options, such as BT5.3, WLAN and NFC, simplify the management of the radios. These features facilitate wireless accessory connections, remote programming and rapid user identity recognition. The 20% reduction in weight and 10% slimming down compared to previous IS series, coupled with advanced ergonomics, further elevate the user experience. Both models operate in extreme work temperatures ranging from -25 to +60°C.
