Dirty electricity Pakke 2 (5 filtere)
Skittenstrømfilterene demper støy fre det elektriske anlegget ved at den fjerner uheldige frekvenser som rir på de rene sinusfrekvensene i strømnettet. Det er særlig sparepærer, lysstoffrør og alt av elektronisk utstyr som lager disse frekvensene. Skittenstrømen måles med en skittenstrømmonitor som puttes i vegguttaket. Man legger til filtere i den sammme kretsen til den ønskede effekten er oppnådd.
Frekvensfilter FF3
FF3 er et bånpass filter tilpasset instrumentene HF35C og HF38B. Med dette filteret er det enkelt å finne hvilke strålingskilder som er dominerende. Ved hjelp av en glidebryter velger du den kilden du er interessert i (f. eks. DECT) og avleser på instrume.
Til HF 35 C, HF 38 B, HF 58 B, HF 59 B.
#Service-specific frequency filter FF3 Recommended for: HF35C, HF38B. The service specific filters always only show the preset radio service, and suppress all other frequencies.
Evaluates each radio service separately
* To be connected between the antenna cable and the antenna input socket of the measurement device (by the operator).
* Cascadable with all amplifiers and attenuators.
* Also allows a broadband measurement without additional transmission loss, which means the filter can remain attached to the measurement device.
* Comprises the most common sources of radiation.Very good selection of the chosen radio services.
* Possible exposures to sheath currents on the cable behind the filter can be additionally suppressed with the help of a free of charge modification of your HF-device. Please do not hesitate to contact us.
Frequency Range: ALL / GSM9 / GSM18 / DECT / UMTS / WLAN
Accuracy: Typical suppression of unwanted frequencies : > 25-30 dB, GSM1800 vs. DECT eff. 20-30 dB.
Power supply: 9 V battery
Frekvensfilter FF6
FF6 er et lav- høy- og bånpass filter anbefalt for HF58B og HF58B-r. Med dette filteret er det enkelt å finne hvilke strålingskilder som er dominerende. Ved hjelp av en glidebryter velger du den kilden du er interessert i (f. eks. DECT) og avleser på inst.

Additional features as compared to the FF3:
* The 50-60 dB suppression of unwanted frequencies is unequalled in this product segment. It allows for a precise analysis of the selected frequency ranges.
* An additional high pass filter applied at 1100 MHz helps differentiating in areas with high levels in the TV bands.
* To be connected between the antenna cable and the antenna input socket of the measuring device (by the operator).
* Cascadable with all amplifiers and attenuators.
* Also allows for a broadband measurement without additional transmission loss, which means the filter can remain attached to the device.
* Perfectly shielded against interferences.
* Possible exposures to sheath currents on the cable behind the filter can be additionally suppressed with the help of a free of charge modification of your HF-device.

Høypass filter HP800_G3
High-pass filter suitable for: HFE35C, HF59B, HFE59B.#
The HP800 increases the measuring accuracy when measuring with the log.-per. antenna in combination with the extremely broad band devices HFE35C and HF59B(Filter included in the scope of supply of the HFE59B).
Why?
The log.-per. antennae are sensitive also for individual frequencies below the specified frequency range. These can be successfully suppressed with the filter, which in turn allows a significantly improved analysis of the measurements with a log.-per. antenna, as the measurements are not impaired by unidentified interference signals.
– This filter helps suppress the lower frequencies. It reaches an attenuation of more than 50 dB (= factor 100,000) below 600 MHz.
– All Gigahertz analysers specified above 800 MHz already come with a similar filter integrated in the basic device. This integration naturally makes no sense for the HFE-types.
– Adaptor plug to be connected to the antenna input socket.
Technical data:
– Accuracy: Attenuation: 10 MHz – 600 MHz < – 50 dB
– Pass band: 0 Hz, 800 MHz – 3000 MHz = -1 dB +/- 0.5 dB
– Return loss: > 12 dB
– Further Questions: Two years warranty
– Weight: 0,03 kg
Scope of delivery:
– High-pass filter
– tightening aid

HF Analyzer HF 59 B (Måler høyfrekvens, proff)
Vårt førsteklasses HF-apparat.
Apparatet har en ekstra bred frekvensrespons, og funksjonene er
beregnet på å møte behovene innen byggebiologien.#
Due to its
extra broad frequency response, this basic device is predestined for an
extension with the UBB27 and for detailed, professional analyses. Its
functions and features are tailored to the needs and practical
experiences of the building biology. Due to its comparably low price, it
is often also used for scientific and industrial purposes – mostly as
kit called HF E 59B – especially in the sector of EMVU and product
development (precompliance).
In addition to the full functionality of the HF58B-r:
–
A frequency range of down to 27 MHz within the basic device – suitable
for the connection of the optionally available antenna UBB27_G3 (the
scope of delivery includes a compensated antenna for 800 MHz up to 2.5
or 3.3 GHz).
– A calibrated extra AC-measurement output for the demodulated signal, and a scalable DC-output.
–
HINT: If you only need to measure above 800 MHz the HF58B-r is the
cheaper and better solution for you. Only with the antenna UBB27
(included in the kit HFE59B) you can in fact measure frequencies below
800 MHz (e.g. digital TV, TETRA, new GSM Channels in Europe).
Technical Data:
–
Frequency Range: A frequency range of down to 27 MHz within the basic
device – suitable for the connection of an optionally available antenna
(the scope of delivery includes a compensated antenna for 800 MHz up to
2.5 or 3.3 GHz)

– Accuracy: Basic accuracy including linearity tolerance : +/- 3dB
Zero offset and rollover +/- 5 digits
–

– Audio Analysis: Identification of pulsed
radiation sources (mobile radio (GSM, UMTS/G3), cordless telephones
(DECT), WLAN (Bluetooth), air-traffic control radar) by means of an
acoustic signal proportional to the modulation frequency
