WSD-5 Handheld Whiteness MeterDetailed product description：

The WSD-5 handheld whiteness meter is suitable for the following industries:

Building materials (cement, silicate, talcum powder, kaolin), daily chemical products (cosmetics, detergents, laundry detergent), ceramics (building ceramics, daily ceramics), flour, salt industry, food, beverage, textile, wool and linen, fiber, chemical industry, plastics, metallurgy, ultrafine powder, papermaking, printing, metrology, commercial inspection, etc.

Detailed parameters: Instrument features:
Observation conditions: 45/0 conditions are convenient to carry and suitable for on-site testing of samples.
Lighting conditions: A high-efficiency light source system with approximate A light source that complies with CIE regulations, capable of measuring up to 100000 times.
By using a 45/0 observation condition, the surface of the object being measured can be eliminated
Measurement mode: Compliant with ISO2470 standard, using the influence of glossiness on the white measurement value.
The R457 (Wr) whiteness reflectance measurement mode instrument adopts a low-power design and can be used with five AA batteries
More than three months.

Test aperture: ¢ 15mm, fast testing speed, can complete one measurement operation within 3 seconds.
Measurement range: Whiteness value (Wr) 0-100. The measurement data is stable and has good repeatability.
Indication accuracy: 0.1 high-definition LCD display with Chinese prompts for operation.
Stability: Zero drift ≤ 0.1, intelligent memory system, after initialization setting of the instrument, generally
When the drift of the indication is ≤ 0.2, there is no need to perform calibration operations such as zero and white adjustment during measurement.
Measurement repeatability: Δ Wr ≤ 0.2 The instrument has an automatic power-off function. If there is no response after the instrument is turned on
Measurement accuracy: If Wr ≤ 1.0, the device will automatically shut down after 20 minutes.
Power supply: Five AA batteries or AC adapter measurement operation error alarm prompt.
Working temperature: 0-40 ° C with data output function, can be connected to a computer or printer.
Instrument size: 220 × 75 × 65 mm. Low battery warning function, which can prompt when the battery is depleted
Instrument weight: 290 g (without battery). The user needs to replace the battery to ensure accurate and effective measurement operation.
