Ludlum Model 2221 Digital Scaler Ratemeter

Description

We have sold a large number of these very versatile Ludlum Scaler/Ratemeters over the years.  They have a built in scaler and easy to access and read settings on the top so you can swap between probes in the field.  They are a staple for decommissioning projects and walk over surveys.
Turn them into Cloud connected GPS Dataloggers by inserting a Counts.Pro  (see Ebay item:
401468071255)
.
See the photo in the listing of the type of survey you can do with this meter enabled with Counts.Pro.
We get these from closed out decomissioning projects and make them ready for you to use.  We are nuclear industry professionals so you never have to worry about the functionality of our meters.  We sell to Nuclear Stations, National Labs, radiopharmaceutical manufacturers, and hobbyists.  We sell worldwide and have been refurbishing meters like this since 2003.
Thanks for checking us out.
Ludlum Model 2221
Ludlum Digital Scaler/Ratemeter
General
purpose ratemeter and scaler with just about every bell and whistle you'll ever need or want.  Capable of driving any probe from a GM to a NaI, or proportional counter. This ultimate tool provides a customary analog display for optimally viewing the count rate and rate of change through all four decades of display. It is accompanied by a digital LCD, which can present either the ratemeter data or be switched over to read the scaler counts. We sell these regularly to our nuclear power customers as a reliable instrument that can drive nearly any meter.
NOTE:  These are Refurbished units.  This is a stock photo.  We can send you a photo of the actual unit you will get.  Having a scaler lets you really assay materials to determine radioactivity.
It is a hand held portable meter that can also be used as a lab instrument to performed timed counts.
When paired with a 2X2 NaI probe it is the standard for taking environmental measurements.
These are regularly used for soil monitoring with walk over surveys, screening of shipments where no contamination is allowed, screening of personnel, and even screening of food samples for contamination.
Paired frequently with a Model 43-37 floor monitor probe on a suitable cart (Ludlum 239-1F or other) for walkover surveys.
What makes this instrument so well liked by experts is its rich array of logically arranged discrete controls on the front panel that permit precise control of the desired measurement. Control functions available include, decade range selection, scaler count time, power on/off, response setting, LCD analog/digital switch, PHA window switch, lamp, audio divide by, audio volume, count zeroing, and scaler start/halt.
The wide range high voltage supply supports a wide variety of detectors with additional threshold and window settings that facilitate switching between gross counts and the energy band of interest. The instrument housing is cast aluminum with a separate battery compartment and accompanying metal handle. This design delivers industrial robustness, quality, capability, and versatility that is difficult to surpass anywhere.
We have detectors, such as 2x2 NaI probes and GM pancake probes, so please ask to purchase one with the Ludlum 2221.
This Meter is Counts.Pro ready!!
You can add a Counts.Pro to this device and turn it into a cloud connected digital ratemeter and datalogger.  Physical documentation of every measurement you ever take is now possible with Counts.Pro.  We help you to record the readings in real time instead of just watching the needle dancing around on your analog screen.  With Counts.Pro you get a datalog of your entire survey with easy access to all your data by emailing from your IOS device.  You can do long term counting and statistical analysys of survey results to determine very low levels of radioactivity and even collect GPS information.  Instead of just a paper saying you did a survey, you can now give your client all the data behind your efforts!  Counts.Pro connects the meter output to your IPhone/IPod/IPad where the processing occurs with our Free Counts.Pro App (available now in the Apple Store).  With Counts.Pro you get a digital file with all your meter readings for the entire time period that you can sync to our cloud server archive or email to anyone. See Ebay listing 401468071255 to add a Counts.Pro to this order, or
