El kit incluye:
- Extech 445580 - Bolígrafo higrotermómetro
- Clip de bolsillo
- Batería de litio de 3 V
- Guía del usuario
El compacto bolígrafo higrotermómetro 445580 es ideal para uso en campo. Una pantalla LCD dual muestra simultáneamente la temperatura de 14 a 50 °C y la humedad del 10% al 90% para una visualización cómoda.
Este bolígrafo de temperatura y humedad de tamaño de bolsillo tiene una función Max/Min que almacena lecturas más altas y más bajas tanto para temperatura como para humedad relativa. La retención de datos "congela" la lectura en la pantalla, y el apagado automático conserva la energía de la batería. Una utilidad de autocalibración integrada permite realizar calibraciones de campo utilizando el kit de calibración RH300-CAL opcional que incluye dos botellas de calibración.
- Rango (% de humedad relativa): 10 a 90%
- Rango (Temperatura): 14 a 50 °C
- Precisión (% de humedad relativa): ±5%
- Precisión (temperatura): ±1.-13.3 °C/1 °C
- Dimensiones: 145 x 30 x 25 mm

I want to preface this review with the caveat that in order to achieve accurate relative humidity readings, this psychrometer will require the use of a 33% and 75% calibration salt kit. While they cost as much as this meter, they at least ensure accuracy, which was NOT achieved through factory calibration. As shown in the review image, the RH% reading is not calibrated we'll out of the box, but that can be expected as calibration can change in storage or shipping.I went through and returned several other psychrometers on Amazon before finally finding this one, which actually worked as described. The entire market is saturated with cheap Chinese clones where a company (sometimes reputable) slaps their name on, or changes the color of, the same generic Chinese psychrometer (often 12 degrees F or more off and unable to be calibrated). This meter, however, is unique in on the market and has the backing of the company that produced it.The calibration procedure with the Extech salt kit is easy. The meter is perfectly sized to fit within their calibration bottles and the directions are clear on how to calibrate both to 33% and 75% relative humidity.The construction of the meter exceed that of the competition as well. While It is still plastic, that plastic feels thicker and more solid than the other models on the market which feel like cheap toys. The meter reacts very quickly to changes in temperature and humidity, possibly sub-second, but does take a good 20 seconds or so to stabilize in a new environment.My goal for the meter was to establish as accurate a baseline reading for Temperature and Relative Humidity as possible for use in calibration many other sensors of varying makes and brands within my home automation system and I can gladly report that the goal has been achieved through this meter.

I just received the above product today. I have gone through the instructions on how to change from F to C which did work however it is already reading E2 error and needs to be recalibrated? According to the instructions this requires a salt reference bottle? Is this something that I now have to purchase? If so, we will likely return the unit. Please advise, thank you.

It does the job. 4 stars cause the price went up a lot.

Kind of a bait and switch. I believed I ordered a 44550 from the photo on the screen with the NIST calibration. I received a 445580 not the same as the photo in the add but it is the number of the instrument ordered. (its still the 44550 photo right now as I write this). In addition I had no concept that the relative Humidity accuracy is + or - 15%, wow, I found that out on the NIST Certificate of Calibration.

Needs to be calibrated for the humidity reading.The calibration bottle cost a bomb,much more than the device itself.DO NOT BUY.Amazon and the seller were kind enough to arrange for a promt refund.One should buy only the thermomter....
