The WPT EX series scales are designed for easy and fast weight determination in laboratory or industrial environments in areas at risk of explosion. Both the weight indicator and the platform are designed to work in these areas. They are powered by a power supply with spark protection, model ZR-02. The power supply is located outside the risk area, via 20 meters of cable. WPT EX balances are designed to operate in zones EX 1 and 2 with mixtures of vapors and explosive gases in the air, group IIB and temperature classes T1, T2, T3 and T4. The scale WPT EX has a 300 × 300 mm or 400 × 500 mm weighing platform made of painted steel and a stainless steel weight indicator with backlit LCD display. The indicator is connected to the platform by cable and has also a wall-mounting bracket.
