I. Introduction to the environmental monitoring station Environmental monitoring stations refer to units that can issue legally valid reports of “water and wastewater†monitoring, “noise†monitoring, “ambient air and exhaust gas†monitoring, and “radiation†monitoring. The general environmental monitoring station shall have the provincial-level measurement certification qualification, and the national-level environmental monitoring station shall have the “Laboratory Approval Certificate of the China National Accreditation Service for Conformity Assessmentâ€. Second, the environmental monitoring station monitoring scope introduction Specifically, it can include: 1. Water and wastewater monitoring: including drinking water, industrial water, domestic wastewater and industrial wastewater. Monitoring items include: water temperature, conductivity, pH, color, odor, suspended matter, turbidity, chemical oxygen demand, BOD5, ammonia nitrogen, total phosphorus, nitrate nitrogen, nitrite Nitrogen, formaldehyde, hexavalent chromium, petroleum, animal and vegetable oils, total bacteria, total coliforms, copper, lead, zinc, cadmium, iron, manganese, nickel, etc. 2. Noise monitoring: (industry enterprise boundary noise, construction site boundary noise, urban area environmental noise, traffic noise, etc.). 3. Ambient air and exhaust gas monitoring: (inhalable particulate matter, total suspended particulate matter, dust, soot or particulate matter, smoke blackness, benzene series, carbon monoxide, sulfuric acid mist, hydrogen chloride, sulfur dioxide, nitrogen oxides, ammonia, lead, cadmium , nickel, tin, cooking industry, soot, etc.). 4. Indoor air quality testing: 19 test items specified in [GB/T18883-2002 "Indoor Air Quality Standards" (formaldehyde, ammonia, hydrazine, TVOC, total number of colonies, benzo[a]pyrene, benzene, toluene, xylene , sulfur dioxide, carbon monoxide, carbon dioxide, nitrogen oxides, respirable particulate matter, fresh air volume, ozone, total intensity of radioactive gamma, etc.). 5. Soil/sediment monitoring: PH, water content, organic matter, copper, lead, zinc, cadmium, iron, manganese, nickel, etc. Third, the environmental monitoring station laboratory equipment configuration list In order to complete the monitoring task, the following laboratory equipments need to be configured: Serial number equipment name application 1 PH meter Measuring pH 2 conductivity meter Measuring the conductivity value of the electrolyte solution 3 Liquid chromatography Qualitative and quantitative analysis 4 Gas Chromatograph Qualitative and quantitative analysis 5 UV-visible spectrophotometer Quantitative analysis of the absorption of monochromatic radiation at different wavelengths by measuring materials 6 Visible spectrophotometer Quantitative analysis of the absorption of monochromatic radiation at different wavelengths by measuring materials 7 Atomic absorption spectrophotometer Quantitative analysis of the absorption of characteristic radiation by the ground state atoms of the measured element 8 Ion chromatograph Suitable for the separation of hydrophilic anions and cations 9 Turbidity meter Turbidity 10 Two-channel atomic fluorescence spectrophotometer Qualitative and quantitative analysis 11 Portable dissolved oxygen meter Determination of dissolved oxygen 12 Ion concentration 13 Translucent smoke meter For measuring smoke 14 Opaque smoke meter For measuring smoke 15 Mercury meter Determination of trace mercury in samples of water, air, soil, minerals, food, organisms and human tissue 16 Field strength meter Field strength 17 Air pollution daily average concentration sampler Atmospheric sampling 18 Multifunctional infrared oil detector Determination of oil in soil and water 19 Blackness meter Blackness 20 Polarograph Qualitative and quantitative analysis twenty one Air sampler Collecting air twenty two Automatic soot (gas) tester Measuring dust concentration in flue or dust duct gas twenty three Pitot parallel parallel smoke sampler Measuring the concentration of soot in the atmosphere twenty four Automotive exhaust analyzer Determination of dust concentration in flue or dust duct gas 25 Car exhaust analyzer Detecting vehicle exhaust 26 CO tester Measuring CO content 27 BOD tester Measuring biological oxygen demand in water 28 COD tester Determination of chemical oxygen demand in water 29 Smoke sampler Collecting smoke 30 Flue gas sulfur dioxide analyzer Analysis of sulfur dioxide content in flue gas 31 Flue gas analyzer Analysis of harmful gases such as sulfur dioxide, nitrogen oxides, carbon monoxide and oxygen concentrations in flue gas 32 Oil concentration analyzer Monitoring, analysis and research on industrial wastewater and rivers, rivers, seawater or other oily materials Note: If you need to purchase the above or other laboratory equipment, please call, the price can be negotiated!
Tiger brand electronic safes are made from high-quality materials that are designed to provide maximum security and durability.
The outer shell of the safe is typically made from solid steel, which is known for its strength and resistance to tampering. The steel is often reinforced with additional layers or plates to provide added protection against drilling or cutting attempts.
The door of the safe is equipped with heavy-duty hinges and locking bolts, which are designed to prevent unauthorized access. These locking mechanisms are typically made from hardened steel or other strong metals to ensure that they cannot be easily compromised.
We manufacture a variety of safes, including Fingerprint Cipher Safe Series, Electronic Cipher Safe Series, Magnetic Card Safe Series, Economic Type Safe Series, Hotel Safes Series, Electronic Digital Keypad Safe Box. We can do OEM or ODM for you. Innovation, excellent and reliability are the core values of our business. These principles today additional than ever form the basis of our success as an internationally active mid-size firm for Electronic Safe Supplier We are looking forward to establishing cooperative relationships with you.
