Applicable scenarios
This sensor is specifically designed for gas analyzers. It can be easily replaced and pre-calibrated, and supports on-site replacement operations.

0393 0150 is a dedicated nitrogen monoxide (NO) gas sensor under the brand Testo. Its full model name is "testo 0393 0150 NO-sensor type LN05i". It is mainly compatible with the testo 340 portable combustion analyzer. The core parameters are as follows based on the official product description and the specifications of the compatible equipment:
1. Core Performance Parameters

Detected gas: Nitrogen monoxide (NO, Nitric Oxide).
Measurement range: Mainly labeled as 0-4000 ppm (some channels label it as 0-3000 ppm, presumed to be differences in batches or regions, refer to the latest official description for the exact specification).
Precision error: ±5 ppm or ±10% (take the larger value between the two as the typical error within the full scale range).
Resolution: 1 ppm (the minimum detectable change in gas concentration).
Response time: T90 (the time it takes to reach 90% response value) < 30 seconds (the response speed after gas diffusion to the sensor under normal detection conditions).
Sensor type: Presumed to be electrochemical principle (suitable for gas detection scenarios of the combustion analyzer, electrochemical sensors are the mainstream type for such applications, featuring high sensitivity and low cross-interference characteristics).
2. Compatibility and Usage Characteristics
Compatible devices: Only compatible with the testo 340 portable combustion analyzer. This device can accommodate up to 4 different types of gas sensors at the same time and supports users to replace them themselves.
Calibration feature: The sensor has built-in pre-calibration data. When replacing, there is no need for additional time-consuming calibration gas balance operations. Just install it and it can be used directly. The calibration data is stored with the sensor and ensures consistent detection.
Flexibility for replacement: Supports immediate replacement without professional tools. Suitable for rapid maintenance in the field.
3. Supplementary Notes
This sensor is a dedicated replacement part for the testo 340 analyzer. It has no independent power supply parameters (depends on the power supply of the analyzer host). The environmental adaptation parameters (working temperature, humidity, etc.) are the same as those of the testo 340 host (typical working temperature: -5°C to 45°C, humidity 0-90% RH without condensation).
There are two labeled measurement ranges of 0-3000 ppm and 0-4000 ppm. When purchasing or using, refer to the product packaging, official datasheet, or confirmation from the supplier for the exact specifications.
The core application scenario is the detection of nitrogen monoxide concentration in the exhaust gas of combustion equipment, such as boilers and industrial furnaces. The emission monitoring of combustion systems in these burning processes.
