SH-21Z type (V10) ultraviolet oil measuring instrument Introduction: The SH-21Z ultraviolet oil measuring instrument is an efficient, environmentally friendly, accurate and fast oil measuring instrument developed in accordance with the national environmental monitoring technical specifications, combined with the environmental pollution situation in China and the needs of various environmental monitoring departments. This instrument replaces the banned carbon tetrachloride extractant in infrared spectroscopy with n-hexane extractant, which fully meets the requirements of the new national standard "HJ970-2018 Water Quality - Determination of Petroleum - Ultraviolet Spectrophotometer". This product has simple operation, good precision, high sensitivity, stable performance, and can meet various application requirements of customers. It can be widely used in industries such as universities, research institutes, sewage treatment plants, environmental monitoring stations, petrochemicals, papermaking, pharmaceuticals, printing and dyeing, textiles, leather, brewing, dairy, electronics, municipal engineering, etc Features: 1. It fully complies with the new environmental protection standards and uses ultraviolet light for detection. The instrument automatically measures absorbance and then calculates the final concentration. The operation is simple and the results are accurate 2. The extraction agent uses n-hexane, which has a much lower impact on humans and the environment than the carbon tetrachloride extraction used in infrared oil measuring instruments 3. Adopting a 10.1-inch high-resolution true color touch screen, the user-friendly and concise menu design makes operation more time-saving. A single interface includes detailed information such as detection time, detection items, absorbance, transmittance, concentration value, wavelength value, curve, etc 4. Measurement items can be automatically or semi-automatically measured 5. The instrument has a scanning function and can evaluate the purity of the blank 6. Built in multiple preset standard curves and support for custom curves 7. Large capacity to store 5 million sets of data 8. Built in thermal printer, achieving integration of detection and data printing, capable of printing current and historical data 9. The instrument has a self checking function, which can calibrate the instrument system 10. With USB interface, it can achieve data transmission function Technical parameters: Measurement indicators: petroleum, animal and vegetable oils, and total oil Display method: 10.1-inch touch screen in Chinese with personalized icon operation interface Wavelength range: 200-400nm Lower detection limit: 0.001mg/L Measurement range: 0.001~1000mg/L Range: Multiple range selection Extractant: n-hexane Measurement time: 20-30 minutes Photometric stability: ≤ 0.001A/10min Repeatability: ± 3% Measurement error: ≤ ± 5% Temperature indication error: ± 5% Temperature field uniformity: ± 0.5 Environmental temperature: 5-40 ℃ Environmental humidity: relative humidity<85% (non condensing) Extraction method: manual extraction Curve parameters: built-in standard curve Printing method: built-in thermal printing Net weight: 10.3Kg Product size: 220 * 120 * 90mm
