The industrial probe set 1 800 °C is suitable for the extractive sampling of flue gas analyzed at high flue gas temperatures of up to 1 800 °C. It can be used in combination with both the testo 340 and the testo 350. Applications The industrial probe set 1 800 °C – in combination with the appropriate measuring instrument – can be used for the following applications: Measuring the furnace atmosphere Emissions measurement for efficiency monitoring / commissioning industrial plants Emissions measurement to monitor prescribed limit values The industrial probe set 1 800 °C consists of the following components: Unheated handle Unheated probe shaft up to 1 800 °C flue gas temperature Unheated gas sampling hose with inline filter The industrial probe set 1 800 °C cannot be extended. It also cannot be upgraded by adding a preliminary filter. For temperature measurements which exceed 1 200 °C, we recommend a Type S thermocouple Ideal for the extractive sampling of flue gas at high flue gas temperatures, e.g. in glass and steel production. The industrial probe kit 1800°C comprises a handle, a probe shaft up to 1800°C flue gas temperature and a 4 m long gas sampling hose, including inline filter (all three unheated).
