ExtechHT200 Heat Stress WGBT Meter, Black

works as advertised. Readings also verified against 4 other meters of varying brands to confirmed consistency and calibration.Note that the unit is very sensitive to electrical interference, so do not use it near transformers or panels since it distorts the results. Also, because this is a lower priced unit, the stabilization time is very long - we used 30 minutes + just to be sure.

EL EQUIPO PRESENTO FALLAS EN LA LECTURA DESDE EL INICIÓ, YA QUE AL ABRIRLO NO MEDÍA LA HUMEDAD RELATIVA. LAMENTABLEMENTE FUÉ ABIERTO DE SU EMPAQUE DOS MESES DESPUÉS DE SU COMPRA, YA QUE SE PRETENDÍA MANDAR A CALIBRACIÓN POR UN LABORATORIO ACREDITADO; POR LO QUE LA GARANTÍA YA NO SE PUDO HACER VALIDA LA GARANTÍA DEL PRODUCTO.

Works great and delivered on schedule. Gets u useful heat stress data for professionals on a tight budget. Feels fragile in the hand though. I’m afraid it can’t take a fall so shoud be handled with care.

Works great.
