Lab liquid Thermometer
Classic 30cm long by 1cm diameter lab thermometer for immersion measurings, eg temperature of liquids. Tempered glass (to withstand temperature range), so fragile and appropriate care required. Comes in sturdy plastic casing. Green spirit. Comes in two temperature ranges - specify which you prefer - the 0C to +110C is safe up to boiling point, but the -20C to +50C , better suited to normal or freezing temperatures or to such processes as cheese-making, is NOT for boiling temperatures.
