A single free standing etching tank for PCB's production from either photo resist board or plain copper clad board. The tank includes a 500W heater and thermostat sensor. It also has a pump fitted, which forces air through two bubble bars to provide an even etching. Separate illuminated switches control the mains power and pump, and a neon indicates heater operation. The switches and neon have splash-proof covers. The temperature is set by adjusting the variable thermostat control knob (optimum for ferric chloride 40 to 50 deg C). Supplied with a syphon and 2 metres of mains lead with a sleeved 13A mains plug. Instructions supplied.
