OU5400 Transmittance Black,0-5.0D Film Density Meter Details:
The OU5400 Transmissive Black Film Density Meter is a specialized quality control instrument for industrial non-destructive testing and medical imaging industries.
It adopts the transmission optical measurement principle to accurately determine the light density (blackness) values of X-ray film, industrial flaw detection films, printing films, and other black films. The measurement range covers 0.00 to 5.00D, meeting the detection requirements of most flaw detection photography and medical radiographic films. It is equipped with a high-speed sampling chip, and can output stable readings in 0.8 seconds. The three-digit red digital screen intuitively displays the density value. The operation is simple and easy to master. The overall structure is stable. The standard measurement light hole is 2mm, suitable for the size of conventional films. The working temperature and humidity range is wide, with low power consumption and strong durability. It is widely used in pressure vessels, bridges, ships, chemical pipelines for non-destructive flaw detection quality inspection, as well as in the quality control of radiographic films in hospitals' radiology departments and the detection of printing plate films. It is a basic standard equipment for controlling the imaging quality of films.
Product Core:
1. Ultra-wide measurement range, covering all scenarios. The density measurement range is 0.00 - 5.00D. It can accurately detect both high and low density film plates, meeting the film inspection standards for various industries such as flaw detection, medical, and printing.
2. Precise and stable reading, with controllable error. The accuracy is ±0.02D for the range of 0 - 3.00D. The error in the high range is strictly controlled, and the reading stability is ±0.02. The measurement data can be traced back and is in line with industry inspection standards.
3. Ultra-fast sampling, one-click measurement. The sampling response time is 0.8 seconds. Press the probe and the reading will be displayed immediately. There is no need for long waiting times. The efficiency of large-scale film inspection is significantly improved.
4. User-friendly and simple operation, durable machine. The three-digit digital display screen shows the reading clearly, with a 2mm standard measurement light hole. The machine body is resistant to knocks and bumps, with a power consumption of only 25W. It is not prone to overheating and malfunction during long-term continuous operation.
5. Wide environmental adaptability, strong versatility. The working temperature is 0℃ - 40℃, and the humidity is ≤85%. There is no condensation. It can be used stably in indoor workshops and laboratories. It is a cost-effective domestic alternative to imported density meters.

FAQ
1. What films can this densitometer test?
--It measures optical density for NDT radiographic X-ray film, hospital radiology film and printing black-white film.
2. What is the maximum measurable blackness?
--Measuring range covers 0.00~5.00D, fits nearly all standard NDT and medical film types.
3. Is calibration required every startup?
-- Zero calibration without sample is recommended each time power on to ensure accurate readings.
