T&D RTR-501: With Internal Temperature Sensor

This wireless internal sensor thermo recorder provides optimum waterproof and dust-proof capabilities. This is the perfect Data Logger for use in harsh environments: whether that may be indoor frozen or refrigerated storage or high humidity, high dust outdoor applications. Moreover, the compact lightweight design means it can be placed just about anywhere.
Download Data via Wireless Communication with a Base Unit.  Recorded data can be downloaded from RTR-500 Series Data Loggers (Remote Units) via wireless communication with a Base Unit. The wireless communication range between a Remote Unit and a Base Unit is about 150 meters [500 ft]. By registering an RTR-500 as a Repeater, it can be used to expand the wireless communication range.

RTR-501/502/505: Maximum of 16,000 readings
16,000 readings means you can record every one second and still log four and a half hours of data; or at a recording interval * of 60 minutes you can keep logging for 666 days. A Base Unit can download via wireless communication one RTR-501, RTR-502, or RTR-505 Remote Unit at full logging capacity (16,000 readings) in about two minutes.
Low Energy Consumption Design

The RTR-500 Series Data Loggers use one Lithium Battery (LS14250). At normal temperature, if recorded data is downloaded once a day or if monitoring is carried out once every ten minutes, the estimated battery life will be about ten months.
Model names which include "L" are designed with a large capacity battery pack. Under the same conditions, L-type models will continue for about four years without the need to change the battery.
* Battery life varies depending upon the type of battery, the measuring environment, and the frequency of communication. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
It is possible to make adjustments to measurements for each RTR-500 Series Remote Unit by using the exclusive application "Adjustment Tools".

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
