The HX15 series two wire remote transmitters measure relative humidity and temperature over a large temperature range (-40 to 180°C). The HX15-W 64 mm (2.5") stainless steel probe is used for wall mounting. The HX15-D 216 mm (8.5") stainless steel duct probe has a removable flange. The probes are connected to housings with 1 m (40") PFA cables. Probes are not field replaceable.

    La Crosse Technologies V10-TH

    The La Crosse V10-TH Wireless Weather Station (Model No. C84343) is absolutely wonderful. The setup was easy with the Quick Setup Guide provided with the unit. The packaging contains additional support information with the website and phone number if there are questions. I especially liked the daily high low readings and the color on the unit! Tech Instrumentation provided great communication as to the availability of the product and shipping details. If fact, it arrived one day prior to the estimated delivery date. I would absolutely recommend this product and Tech Instrumentation for anyone looking for an indoor/outdoor weather station!


    I needed a replacement as my original sensor no longer worked. This one works fine.

    Excellent Customer Service!

    I can't way enough about the customer service at Tech Instrumentation. I was looking for a hard to find specialty part, which the manufacturer told me would need to be custom made. After calling and speaking with a representative at Tech Instrumentation, the part was located and order was filled, right over the phone. Delivery was prompt, and instrument is working great. Highly recommended company for lab supplies!

    Worked great

    Put batteries in and worked great
