The Milwaukee TH300 is a compact digital thermometer designed for accurate and convenient temperature measurement in water and other applications. Supplied with a stainless-steel probe connected to the meter by a flexible 1-metre cable, it makes checking temperatures in difficult-to-reach areas straightforward.

For aquarium keepers, the TH300 provides a convenient way to check aquarium water temperature, compare replacement water before water changes and monitor temperatures in different tanks.

With a wide measurement range of -50.0 to 150.0°C, a clear digital display and 0.1°C resolution, the TH300 is also suitable for brewing, winemaking, food preparation, educational experiments and general laboratory use.

Ideal for aquarium temperature checks

Temperature is an important water-quality parameter in aquarium keeping. Monitoring it helps ensure that aquarium water and replacement water are within the intended temperature range for the livestock being kept.

The Milwaukee TH300 can be used to:

• Check the temperature of freshwater aquarium water.

• Compare aquarium temperature with replacement water before a water change.

• Check water temperature in breeding and quarantine tanks.

• Monitor the temperature of prepared water.

• Take measurements in containers and other hard-to-reach locations.

The 1-metre cable allows the stainless-steel probe to reach into a tank or sample while the digital display remains conveniently positioned outside.

Stainless-steel probe with 1-metre cable

The TH300 is supplied with a general-purpose stainless-steel temperature probe connected to the meter by a flexible 1-metre cable.

Simply place the probe in the sample being measured and allow the reading to stabilise.

The stainless-steel probe is durable, easy to clean and suitable for repeated temperature measurements in water and other samples.

Keep the meter housing and electrical connections dry. The TH300 is a portable thermometer, not a waterproof aquarium controller designed for permanent installation.

Wide temperature measurement range

The Milwaukee TH300 measures temperatures from -50.0 to 150.0°C, making it suitable for a wide range of applications.

Its 0.1°C resolution allows users to see temperature changes in small increments.

The specified accuracy is ±0.5°C between -20°C and 90°C.

Clear digital display and simple operation

The TH300 features a large LCD display designed to make temperature readings easy to see.

Its straightforward operation makes it suitable for aquarium keepers, laboratories, brewing applications and general-purpose temperature checks.

The meter is supplied with a battery and has an approximate battery life of one year under normal use.
