Vintage temperature gauge - 0 to 120F The British Teltherm Co. Ltd, Auckland

LAST CHANCE

The British Teltherm Co. Ltd was a New Zealand-based company with a long history in the instrumentation and engineering sector. They were founded in Auckland and specialised in manufacturing and supplying a wide range of gauges, thermometers, and industrial control equipment.

Local Manufacturing: The company's name, "British Teltherm," reflected its origins and the British standards it adhered to, but it was a proudly New Zealand-based manufacturer. Their products were used extensively in local industries, including dairy factories, breweries, and various manufacturing plants.

The Gauge: A range of 0-120°Fahrenheit (approximately -17 to 49°C) it was originally used in a flour mill to monitor the temperature in a pre-cooking kiln for making rolled oats.

The fact that it was made in Auckland adds to its local historical significance.

Interesting curiosity or useful working gauge if you don't the scale being in F ( ideal as an accurate temperature gauge for someone old or American enough to still think in Fahrenheit ).
