On a vessel, it is used to monitor the onboard environment to protect sensitive equipment, cargo, and crew quarters from excess moisture or heat. The IMPA 370251-coded instrument is a recognized standard tool in maritime supply.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this psychrometer suitable for saltwater marine environments?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This wet and dry bulb thermometer is specifically designed for marine use, with a durable wood plastic composite board construction that resists moisture, salt spray, and seawater exposure — ensuring stable, accurate performance during extended voyages.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I read relative humidity using this thermometer?\u003c\/h4\u003e\n\u003cp\u003eA: Record the temperatures shown on both the wet bulb and dry bulb thermometers, then calculate the difference between the two readings. Using a standard psychrometric chart or hygrometric table, cross-reference the dry bulb temperature with the wet\/dry difference to determine the relative humidity percentage.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this instrument require special maintenance?\u003c\/h4\u003e\n\u003cp\u003eA: This psychrometer is engineered for low maintenance. Ensure the wick on the wet bulb is kept clean and moist with distilled water before each use, and periodically inspect the composite housing for any build-up of salt deposits. Rinse gently with fresh water as needed to maintain accuracy.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
