The Vaisala HUMICAP® Handheld Humidity and Temperature Probe, model code HMP80 N1E1S0, is 100% designed, engineered, and manufactured in Finland by Vaisala Oyj – the worldwide gold standard in meteorological and industrial environmental measurement technologies. Optimized for seamless portable operation alongside the Vaisala Indigo80 Handheld Indicator, the HMP80 functions as an ultra-precise portable reference standard. It empowers service engineers, HVAC commissioning specialists, and QA/QC auditors to perform instantaneous spot-checking, in-situ loop checks, and accredited field calibration of permanently installed humidity instruments directly in the process without dismounting equipment.

At the technical core of the HMP80 N1E1S0 is Vaisala's proprietary capacitive thin-film polymer sensor, the HUMICAP® R2C, paired with an ultra-precise Pt100 RTD Class F0.1 platinum temperature sensor complying with IEC 60751 standards. This dual-sensing architecture delivers laboratory-grade measurement integrity: achieving an outstanding relative humidity accuracy of ±0.8 %RH across the 0 … 90 %RH range, alongside a temperature accuracy of ±0.1 °C (±0.18 °F) at +23 °C. A defining hallmark of the HUMICAP® sensor is its 100% tolerance to liquid water condensation, bolstered by integrated sensor warming routines and thermal chemical purge cycles. Consequently, the probe demonstrates superior chemical resilience against rigorous industrial cleaning vapors (such as 70% Isopropyl alcohol, Acetone, and non-condensing vaporized hydrogen peroxide H2O2), fully preserving baseline measurement calibration and preventing long-term sensor drift.

Structurally engineered for demanding field duty, the HMP80N configuration features a standardized 106 mm AISI 316L stainless steel probe shaft coupled with an ergonomic, slip-resistant handle molded from Polyamide (PA) and thermoplastic elastomer (TPE), achieving an IP66 ingress protection rating when mated with its connection cable. This specific order code, HMP80 N1E1S0, comes comprehensively equipped with a premium accessory bundle: a high-durability Slotted MIM (Metal Injection Molding) stainless steel filter with protective membrane (P/N: ASM214606SP), a dedicated 1.5-meter M12-to-M12 industrial probe connection cable (P/N: 272075SP), and a traceable factory calibration certificate. Offering out-of-the-box compatibility with the Indigo80 indicator, Indigo500/200 host transmitters, and direct PC connectivity via Vaisala Insight Software, the HMP80 stands as the definitive portable diagnostic probe for mission-critical industrial manufacturing facilities.
