The Vaisala Indigo80 Handheld Indicator and Data Logger (Configuration Model: INDIGO80 A0A1A1N0), engineered by Vaisala (Finland)—a global leader in environmental and industrial measurement—represents a benchmark handheld diagnostic and data logging tool. Designed to maximize operational efficiency, measurement integrity, and field versatility, the Indigo80 serves as a portable diagnostic hub for maintenance technicians, laboratory specialists, and quality control (QA/QC) personnel. It enables direct on-site spot-checking, real-time trend visualization, rapid loop calibration, and comprehensive configuration of Vaisala Indigo-compatible smart measurement probes and transmitters without requiring a PC in the field.

A core advantage of the Indigo80 is its dual-probe architecture, which features two independent M12 industrial ports allowing simultaneous connection and readout of two smart probes. Operators can synchronously monitor multiple critical parameters, including relative humidity (%RH), temperature (°C/°F), dew point temperature (Td), carbon dioxide (CO2) concentration, vaporized hydrogen peroxide (H2O2), and moisture dissolved in transformer or lubrication oil. All measurement telemetry is rendered on a high-contrast 2.7-inch transflective TFT LCD color screen with ambient backlight control, guaranteeing crystal-clear readability under direct outdoor sunlight as well as in dimly lit mechanical utility corridors. The multilingual menu-driven interface (available in 10 languages) features tactile physical pushbuttons engineered for seamless single-handed navigation even while wearing heavy protective gloves.

Beyond instantaneous field measurement, the Indigo80 functions as a high-capacity autonomous data logger, storing up to 5.5 million individual measurement values in internal non-volatile memory with customizable logging intervals ranging from 1 second up to 12 hours. Stored logs can be exported directly to a host computer as standard CSV files via the integrated USB-C interface without requiring specialized software suites. Mechanically constructed for severe field duties, the indicator combines an EN AW-6082 T6 anodized aluminum chassis with a fiberglass-reinforced polycarbonate and TPE rubber back cover, offering exceptional resistance against harsh industrial chemicals, solvent splashes, and accidental mechanical impacts.

This specific configuration, INDIGO80 A0A1A1N0, comes fully outfitted with a professional accessory package including an M12-M8 transmitter service cable (P/N: 262195SP), an M12-M12 probe connection cable (P/N: 272075SP), a USB-C charging and communication cable, and a heavy-duty weatherproof carrying case (P/N: ASM214759) custom-molded to house the Indigo80 alongside HMP80/DMP80 handheld probe series. It is an ideal portable measurement standard for GMP pharmaceutical plants, semiconductor cleanrooms, EV battery production lines, building automation HVAC auditing, and industrial compressed air desiccant dryer testing.
