New Zap Checker Model 185

Broadband RF Receiver Meter

Model 185 Zap Checker. $159.00

The Zap Checker 185 is a rugged hand held radio frequency detector that spans 3 MHz to over 5 GHz. It uses state of the art components designed for wireless communication products, this gives the Model 185 a unique sensitivity which allows it to detect weak signals at ambient, baseline levels.

This is the best broadband RF Receiver/Meter available today.

1. Superb sensitivity, enabling the detection of ambient signal levels and all transmissions that exceed that level.

2. Adjustable sensitivity control of more than 20 dB.

3. Broadband detection capability spanning 3 MHz to over 5 GHz.

4. Detection Modes
LINEAR for far-field detection of the weakest signals 10 dB dynamic signal range
LOG for near-field localization without overloading 60 dB dynamic range
MID for intermediate detection and localization 25 dB dynamic signal range

5. Detection and differentiation between analog RF signals and digital transmissions. Enhances the detection of cell phones, wireless phones and computer wireless signals.

6. Wide dynamic range, 60 dB in logarithmic mode.

7. On analog meter combined with LED display allowing night and distance viewing as well as pulse detection.

8. An intensity-modulated silent vibrator that gives variable vibration intensity depending upon the signal strength. This is a switch-enabled feature.

9. Fixed internal antennas for repeatable measurements.

10. Small physical size, fits in your hand, fits in your pocket.

11. Long battery life, 80 hours with 2 AA batteries.

When you need to track down an RF source this is the first tool to reach for. The wideband response and superb sensitivity will sniff out any RF source.

What you get. The Zap Checker Model 185 as pictured, new in box with user manual.
One year Warranty.

Model 270 Zap Checker

Model 270 Zap Checker. $269.00

Model 270 with External 1.8 - 6.4 GHz Directional Log P Antenna. $329.00

Zap Checker Model 300

With 1.8-6.0 GHz LPDA

Advanced Technology RF Detection

The Model 300 takes full band RF detection to new levels. With a new RF preamplifier section it boasts extraordinary sensitivity, better than -75 dBm at 2.4 GHz; right where you need it most.

Broadband detection:
1.0 MHz to 8.0 GHz.
Selectable Antenna Options:
2 fixed omni-directional internal antennas for repeatable measurements.
SMA Switch selected Connector for 50 ohm DC isolated external antenna.

Now 3 Detection Modes:
Linear Mode; 12 dB of weakest signal levels.
Log Mode; 60 dB full meter range.
MID Mode; high sensitivity with excellent dynamic range.

Analog Meter and Low / Peak LED Display:
The unique hybrid display makes this an extremely useful instrument for distant and night detection work.

As always a silent vibrator mode; for those times you need to be discrete.

The unique feature of the Zap Checker 300 is the ability to use special antennas and band pass filters through a SMA coaxial input connector. Depending upon the frequency and directionality of the externally connected antenna, the ZC 300 becomes a highly directional frequency-specific instrument which is ideal for counter-surveillance detection and for aligning transmitter/receiver antennas over far distances. The included 1.8 to 6.4 GHz LPDA antenna is quite directional and provides about 6 dB gain on axis within 5 degrees.

What you get, the Zap Checker 300 as shown with the 1.8 to 6.4 GHz LPDA.
One year manufacturer warranty.

Zap Checker Model 190

Wireless Signal Detector

The ZC 190B is a quality instrument that detects and displays RF (Radio Frequency) signal levels with uniquely high sensitivity, similar to a broadband receiver. It provides Linear and Logarithmic measurements of RF signals over a broad span of frequencies. The ZC 190B allows the user to view signal strength measurements, to hear the difference in signal levels, and to distinguish between Analog and Digital signals. The ZC 190B comes complete with a plug-in Mini-speaker, ear buds with a volume control and a handy soft carrying case.

1. Superb sensitivity 45 uV (microvolts) at 50 ohms (about -75 dBm)

2. Bandwidth < 1 MHz to to over 8 GHz useable frequency range

3. Sensitivity Controller 20 dB, (10 to 1) signal control range

4. Detection Modes
LINEAR for far-field detection of the weakest signals 12 dB dynamic signal range
LOG for near-field localization without overloading 60 dB dynamic range
MID for intermediate detection and localization 25 dB dynamic signal range

5. Analog Mode For detecting and measuring continuously transmitted signals

6. Digital Mode For peak-detecting, identifying and measuring digitally pulsed signals

7. Audio Output VCO - Audio-frequency changing Voltage Controlled Oscillator for hearing differences in detected signal levels by different pitch levels AM – Enhanced Amplitude Modulation detection and RF signal characterization

8. An intensity-modulated silent vibrator that gives variable vibration intensity depending upon the signal strength. This is a switch-enabled feature.

9. Audio Output Jack IV P-P, 45 mw stereo 3.5 mm audio output jack > 15 ohm impedance

10. Analog Meter Display Visual indication of changes and levels of RF signals

11. LED Display Gradually dimming and enhanced LED lighting depending upon detected signal strength
