As a food inspector or quality supervisor, you are excellently equipped with the PTB-approved testo 112. The temperature measuring instrument is suitable for official inspection measurements, is so far as you order the initial conformity assessment when purchasing.

The testo 175 T2 temperature data logger is ideally suited if you want to use one instrument to monitor air temperature and to record additional temperature values (e.g. core temperature) on a second channel at the same time. In particular, it is the perfect solution for parallel temperature control of the ambient conditions and the goods themselves when storing food.

The data logger testo 176 H1 allows the monitoring of temperature and humidity in warehouses and buildings. With the testo 176 H1, you can examine whether mould in a house or apartment has been caused by insufficient ventilation or by building damage.

With this kit, you’ll be ready to start your measurements in the commissioning, servicing and maintenance of refrigeration and air conditioning systems and heat pumps straight away: You will get the testo 550s smart digital manifold with Bluetooth and 2-way valve block, two fixed cable clamp temperature probes (NTC) and a robust transport case. Additional Bluetooth probes, e.g. for wireless measurements of temperature and vacuum, are available separately.

Start your wireless measurements on refrigeration and air conditioning systems and heat pumps straight away. The practical kit containing the testo 558s digital manifold with Bluetooth connection to the clamp meter and to the temperature and vacuum probes offers the ideal tools for everyday tasks. The testo 558s offers intuitive operation thanks to its touchscreen and clear measurement graphs on a large colour display. In addition to the touchscreen, the manifold can also be operated via keys when working with gloves. Thanks to its A3 and A2L compatibility, high robustness with IP54 and hybrid charging system comprising rechargeable and non-rechargeable batteries, the manifold is ideal for every situation.

Fast, robust and easy to use: simply hold the air temperature probe in the environment being measured &ndash; and, thanks to the exposed sensor in the probe shaft, you will obtain the air temperature value after only a short response time. The measurement result can be optimized by moving the probe through the air at approx. 1.5 m/s.&nbsp;

Use the robust air temperature probe with exposed sensor (NTC) to measure air temperature with a short response time. It can be connected to a wide range of measuring instruments.
