Temperature and Humidity Sensor

I am looking for an inexpensive temperature and humidity transmitter. Evironment is not harsh (people work in this
area.) I have used Vasalia in the past for explosion proof
areas but these are probably an overkill. Need 4-20ma output
for both temp and humidity.

I used a Omega HX93C several years ago that was 4-20ma out for both signals but I do not remember how much it cost.

Thanks, that should work nicely. They cost around $300.00.. sounds about right.
